Titanium Sheet for Heat Exchanger Plates | Grade 1 & 2<\/h1>\n

Direct answer:<\/strong> DAXUN supplies titanium sheet for plate heat exchanger plates in sheet, strip, coil, and cut-blank form. We do not treat raw ASTM B265 material as a finished, interchangeable heat-transfer plate. Grade 1 is often preferred for demanding corrugation pressing because of its higher ductility, while Grade 2 offers higher strength and remains widely used. Your drawing must define the starting gauge, minimum thickness after forming, plate geometry, surface, and inspection requirements.<\/p>\n

When you ask us for titanium plate for a plate heat exchanger, one early question saves a great deal of confusion: do you need flat material for pressing, or a finished corrugated replacement plate for a named exchanger model? The alloy may be the same, but the manufacturing route, responsibility, and acceptance criteria are not.<\/p>\n

For a raw-material inquiry, we can review the following supply scope. Exact availability, dimensions, tolerances, testing, and processing remain subject to technical review and mill confirmation.[7]\\<\/p>\n

The table describes material supply, not finished-plate certification. The plate stamper or heat exchanger OEM remains responsible for the die, corrugation, ports, gasket groove, joining, pressure design, and validation of the completed component.<\/p>\n

Titanium Sheet Is Not the Same as a Finished Heat-Transfer Plate<\/h2>\n

In a plate heat exchanger, the word plate<\/strong> describes the corrugated component that separates the two fluids. In ASTM B265, strip, sheet, and plate<\/strong> are raw flat-product forms. Many thin heat-transfer plates therefore begin as ASTM B265 sheet or strip, even though buyers casually call the material \u201ctitanium plate.\u201d[1]<\/p>\n\n\n\n\n\n\n\n
Purchasing term<\/td>\nWhat it usually means<\/td>\nWhat your RFQ must define<\/td>\n<\/tr>\n
Titanium sheet<\/td>\nThin, wide flat-rolled material supplied as sheets<\/td>\nGauge, width, length, tolerance, surface, flatness, and rolling direction<\/td>\n<\/tr>\n

Although buyers often request titanium plates for plate heat exchangers, the mill product may actually be thin sheet or strip supplied for subsequent pressing. If you need a finished replacement plate, the exchanger manufacturer, model, plate code, hole arrangement, pattern, thickness, and gasket details are essential. A grade name alone cannot establish interchangeability.<\/p>\n

Why Use Titanium Sheet for Plate Heat Exchanger Plates?<\/h2>\n

Titanium develops a stable protective oxide film in the presence of moisture or suitable oxidizing species. This gives commercially pure titanium strong resistance in many aerated waters, seawater systems, neutral chloride solutions, and oxidizing process environments.<\/p>\n

The advantage is not unusually high thermal conductivity. Grade 1 and Grade 2 titanium both have typical room-temperature thermal conductivity of approximately 22 W\/m\u00b7K<\/strong>.[3][4] Plate heat exchangers achieve efficient heat transfer through thin material, corrugated channels, large effective area, turbulence, and controlled pressure drop. Titanium earns its place mainly by allowing that thin heat-transfer wall to survive compatible corrosive service.<\/p>\n

For equipment users, this can mean lower corrosion risk than common stainless steels in correctly assessed seawater duties, good resistance to erosion-corrosion in many water systems, low density, and longer service intervals.<\/p>\n

However, \u201ctitanium is seawater resistant\u201d is only the beginning of a selection discussion. Wall temperature, pH, crevices, deposits, fluoride, reducing conditions, galvanic coupling, and cleaning chemicals still matter.<\/p>\n

\"\"<\/p>\n

Choosing Between Grade 1 and Grade 2 for Corrugated Plate Pressing<\/h2>\n

Both Grade 1 and Grade 2 are commercially pure titanium. Tighter oxygen and iron limits give Grade 1 lower strength and greater ductility. By comparison, Grade 2 permits more oxygen and iron, which increases strength but can also increase press load and springback.<\/p>\n

TIMET identifies its ASTM Grade 1-equivalent material as suitable where maximum formability is required, specifically including plate-type heat exchangers. The company describes its Grade 2-equivalent material as an industrial grade used in seawater systems and heat exchangers.[3][4]<\/p>\n\n\n\n\n\n\n\n\n
Grade<\/td>\nUNS<\/td>\nPractical reason to consider it<\/td>\nWhat still needs approval<\/td>\n<\/tr>\n
ASTM Grade 1<\/td>\nR50250<\/td>\nHigh ductility for deep or demanding corrugation pressing<\/td>\nStrength window, pattern depth, local thinning, rolling direction, and finished-plate test<\/td>\n<\/tr>\n
ASTM Grade 2<\/td>\nR50400<\/td>\nHigher strength with good industrial formability<\/td>\nPress load, springback, die qualification, minimum formed thickness, and gasket-groove accuracy<\/td>\n<\/tr>\n
ASTM Grade 7<\/td>\nR52400<\/td>\nGrade 2-based composition with palladium for selected reducing or crevice-corrosion conditions<\/td>\nCorrosion review, OEM approval, formability, availability, and cost<\/td>\n<\/tr>\n
ASTM Grade 11<\/td>\nR52250<\/td>\nGrade 1-based composition with palladium for selected corrosion conditions<\/td>\nProject-specific approval; it is not an automatic upgrade for every brine duty<\/td>\n<\/tr>\n
ASTM Grade 12<\/td>\nR53400<\/td>\nTi-Ni-Mo alloy with improved resistance in some hot-brine or reducing conditions<\/td>\nDifferent forming response, press qualification, and design approval<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Grade 1 is not automatically more corrosion resistant than Grade 2 simply because it is purer. In many oxidizing chloride environments, both depend on the titanium oxide film.<\/p>\n

We normally begin the Grade 1 versus Grade 2 discussion with formability and strength, then check the actual corrosion and equipment requirements.<\/p>\n

Grade 1 and Grade 2 Chemistry<\/h2>\n

TIMET datasheets publish the following limits for materials equivalent to ASTM Grade 1 and Grade 2.[3][4] Contract acceptance must follow the ASTM B265 edition stated in the purchase order, any additional customer restrictions, and the actual MTC.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

The TIMET datasheets state that hydrogen content depends on product form. The purchase specification and MTC should define the applicable requirement and reporting basis.<\/em><\/p>\n

Ordinary handheld XRF cannot reliably separate Grade 1 from Grade 2 because oxygen is an important part of the grade difference and is not measured by conventional handheld XRF.<\/p>\n

PMI can support identity and contamination checks, but grade release should rely on heat traceability, the MTC, and an appropriate laboratory method when independent verification is required.<\/p>\n

Typical Mechanical and Physical Data<\/h2>\n

The following room-temperature values explain the forming difference between the grades. They are representative TIMET data, not guaranteed ASTM B265 acceptance values.[3][4]<\/p>\n\n\n\n\n\n\n\n\n

Actual certificate values can differ from these typical figures while complying with the ordered standard.<\/p>\n

If stable pressing requires a restricted tensile range, yield range, elongation, hardness, grain size, r-value, n-value, or forming trial, state it before quotation. Such controls are not automatically included in a standard ASTM B265 order and remain subject to technical review and mill confirmation.<\/p>\n

\"\"<\/p>\n

Thickness, Tolerance, and Formability<\/h2>\n

There is no universal gauge for titanium sheet for plate heat exchanger plates. Pressure, plate area, contact pattern, corrugation depth, design temperature, forming strain, and equipment code all influence the starting thickness.<\/p>\n

One official Alfa Laval product listing for a T20-P\/AQ8P titanium channel plate documents a thickness of 0.5 mm<\/strong>.[6] This is an example from a specific model, not a general design rule. Your OEM drawing should control the starting gauge and the minimum acceptable thickness after forming.<\/p>\n\n\n\n\n\n\n\n\n\n\n
Requirement<\/td>\nWhy it matters to pressing<\/td>\n<\/tr>\n
Nominal starting gauge<\/td>\nEstablishes the flat feedstock entering the press<\/td>\n<\/tr>\n
Thickness tolerance<\/td>\nAffects press force, local thinning, plate-pack dimension, and pressure performance<\/td>\n<\/tr>\n
Across-width thickness profile<\/td>\nCan influence corrugation depth and consistency across a wide blank<\/td>\n<\/tr>\n
Minimum formed thickness<\/td>\nProtects the most highly strained corrugation, port, or gasket-groove area<\/td>\n<\/tr>\n
Camber, coil set, and flatness<\/td>\nAffect strip tracking, blank positioning, and repeatable feeding<\/td>\n<\/tr>\n
Edge and burr limit<\/td>\nHelps protect tooling and prevent cracks from starting at the blank edge<\/td>\n<\/tr>\n
Rolling direction<\/td>\nCan influence forming behavior and should match the qualified blank orientation<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

\u201cPress quality\u201d is not a separate ASTM grade. It is a purchase description that must be converted into measurable requirements.<\/p>\n

Therefore, the purchaser should confirm the exact gauge, width, coil weight, tolerance, profile reporting, and forming controls for each order rather than infer them from a general product range.<\/p>\n

ASTM B265 and Equipment Responsibilities<\/h2>\n

At the source-review date for this article, ASTM lists ASTM B265-25<\/strong> as the active specification for annealed titanium and titanium-alloy strip, sheet, and plate.[1]<\/p>\n\n\n\n\n\n\n\n\n

Equipment code and design dossier<\/td>\nPressure, temperature, joining, examination, testing, and final conformity<\/td>\nRaw-material production unless linked through the material specification<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Supplying ASTM B265 or ASME SB-265 material does not certify the completed plate heat exchanger.<\/p>\n

The equipment manufacturer remains responsible for forming qualification, joining, gasket selection, pressure calculations, final examination, pressure testing, and any applicable ASME, PED, or other regulatory conformity.<\/p>\n

Surface and Inspection Requirements<\/h2>\n

A sheet can meet chemistry and tensile requirements yet still cause trouble in a high-volume press. Scratches, pits, rolled-in particles, uneven pickling, excessive roughness, waviness, coil set, and burrs can disturb lubrication, mark the tool, initiate tearing, or interfere with a gasket track.<\/p>\n

ASTM B600 provides useful guidance for removing shop soils, oxide, scale, and foreign contamination from titanium surfaces.[2] The buyer must still define the surface appearance, roughness where relevant, edge condition, cleanliness, and defect acceptance criteria.<\/p>\n

Third-party inspection<\/td>\nMust be agreed before quotation, including body, location, hold points, scope, and cost<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Ultrasonic testing should not be added automatically simply because the material is titanium. For thin sheet, the method, calibration, detectable defect size, coverage, and acceptance criteria must be technically suitable and stated by the responsible OEM or purchaser.<\/p>\n

Third-party inspection can be discussed before quotation. Please state the inspection body, hold points, test scope, acceptance criteria, certificate format, and inspection location clearly.<\/p>\n

How Titanium Sheet Is Typically Produced and Supplied<\/h2>\n

Depending on the order, a production mill selected for the required grade, dimensions, and documentation may produce the titanium sheet. DAXUN then supplies the material within the processing, inspection, traceability, and packing scope confirmed in its quotation.<\/p>\n

The following is a typical industry route, not a claim that every operation occurs on one DAXUN-owned line.<\/p>\n\n\n\n\n\n\n\n\n
Stage<\/td>\nTypical activity<\/td>\nPurchasing control point<\/td>\n<\/tr>\n
1. Contract and mill review<\/td>\nConfirm grade, specification, gauge, width, quantity, surface, and supplementary requirements<\/td>\nResolve raw-material and finished-plate responsibilities before production<\/td>\n<\/tr>\n
2. Melt, hot conversion, and cold reduction<\/td>\nProduce traceable feedstock and roll it toward final gauge<\/td>\nChemistry, reduction route, and gauge consistency affect later forming behavior<\/td>\n<\/tr>\n
3. Annealing and surface finishing<\/td>\nRestore ductility and remove process oxide as required<\/td>\nCondition, grain response, cleanliness, and surface consistency matter to pressing<\/td>\n<\/tr>\n
4. Slitting, leveling, or blank cutting<\/td>\nProduce the ordered coil, sheet, strip, or blank dimensions<\/td>\nControl edge, burr, camber, flatness, rolling direction, and identity transfer<\/td>\n<\/tr>\n
5. Final inspection and packing<\/td>\nReview documents, dimensions, surface, marking, and protective packing<\/td>\nKeep the released lot traceable and protect thin surfaces during transport<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

When your press program needs more than standard compliance, tell us before mill planning. We can then determine whether a tighter mechanical window, special report, trial quantity, or blank-level traceability is technically and commercially available.<\/p>\n

Corrosion Boundaries That Still Need Review<\/h2>\n

Commercially pure titanium performs well in many aerated chloride and seawater environments, but it is not immune to every condition.<\/p>\n

Published corrosion data show that unalloyed titanium may become susceptible to crevice corrosion in hot, concentrated brines under severe oxygen-depleted crevice conditions. The threshold depends strongly on pH, temperature, crevice geometry, and solution chemistry.[5]<\/p>\n\n\n\n\n\n\n\n\n\n\n
Service factor<\/td>\nWhy the project team needs it<\/td>\n<\/tr>\n
Both fluid compositions and concentrations<\/td>\nA service name such as \u201cseawater\u201d or \u201cbrine\u201d does not describe every corrosive species<\/td>\n<\/tr>\n
Normal, upset, and shutdown pH<\/td>\nLow-pH solution trapped in a crevice can behave differently from the bulk fluid<\/td>\n<\/tr>\n
Maximum calculated wall temperature<\/td>\nLocal metal temperature can govern crevice behavior more than outlet temperature<\/td>\n<\/tr>\n
Gasket grooves, contact points, deposits, and fouling<\/td>\nRestricted areas can become oxygen-depleted crevices<\/td>\n<\/tr>\n
Fluoride or HF, including cleaning chemicals<\/td>\nAcidic fluoride solutions can attack titanium rapidly<\/td>\n<\/tr>\n
Dissimilar metals and cathodic protection<\/td>\nGalvanic current can damage less noble metals and, under some conditions, promote hydrogen uptake by titanium<\/td>\n<\/tr>\n
Cleaning chemistry and cycle<\/td>\nConcentration, temperature, duration, and rinsing must suit both titanium and the gasket<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

For more severe reducing or crevice conditions, the project team may evaluate Grade 7, Grade 11, Grade 12, or another corrosion-resistant titanium grade. The exchanger OEM and corrosion engineer should make the decision after reviewing actual process and cleaning data.<\/p>\n

Gasket compatibility remains a separate decision. NBR, EPDM, HNBR, and FKM variants respond differently to heat, oils, oxidants, chemicals, and cleaning cycles. Selecting titanium does not automatically select the gasket.<\/p>\n

Frequently Asked Questions<\/h2>\n

What titanium grade is commonly used for plate heat exchanger plates?<\/h3>\n

Grade 1 is often chosen for demanding cold pressing because of its high ductility. Grade 2 offers higher strength and also sees broad heat-exchanger use.<\/p>\n

The die, pattern depth, minimum formed thickness, corrosion conditions, and OEM approval determine the final choice.<\/p>\n

Does DAXUN supply finished corrugated replacement plates?<\/h3>\n

This article describes sheet, strip, coil, and cut-blank supply. A finished replacement plate requires model-specific tooling, geometry, ports, gasket details, and pressure validation.<\/p>\n

Any finished-plate request must be reviewed as a separate scope.<\/p>\n

Is 0.5 mm the standard titanium sheet thickness?<\/h3>\n

No. It is a documented gauge in a specific Alfa Laval titanium channel-plate listing, but it is not universal.<\/p>\n

Use the OEM drawing to specify both the starting gauge and minimum thickness after forming.<\/p>\n

Can handheld XRF distinguish Grade 1 from Grade 2?<\/h3>\n

Not reliably by itself. Conventional handheld XRF does not measure oxygen, an important difference between the grades.<\/p>\n

Use MTC review, heat traceability, and a suitable laboratory method when verification is required.<\/p>\n

Does ASTM B265 certify the finished heat exchanger?<\/h3>\n

No. ASTM B265 specifies requirements for the raw titanium product.<\/p>\n

The equipment manufacturer remains responsible for forming, joining, gaskets, calculations, final examination, pressure testing, and equipment-code compliance.<\/p>\n

What should be agreed before third-party inspection?<\/h3>\n

Name the inspection body, inspection location, hold and witness points, document review, tests, sample frequency, acceptance criteria, report format, and cost before quotation.<\/p>\n

Send DAXUN Your Plate-Pressing Requirement<\/h2>\n

If you have a drawing, send the required grade, starting gauge, blank or coil dimensions, rolling direction, surface, tolerance, and inspection requirements with it.<\/p>\n

If you are still comparing Grade 1 and Grade 2, include the fluid chemistry, maximum wall temperature, pressure, pattern depth, and annual volume.<\/p>\n

For titanium sheet for plate heat exchanger plates, we aim to supply material that matches the agreed forming and inspection requirements, with the processing, documentation, traceability, and packing scope clearly defined before production.<\/p>\n
