商品詳細

The global leader in commercially pure titanium rod manufacturing services

Daxun, specializing in the production of alloy titanium rods for extreme environments—Grade 7 titanium alloy rods.

Grade 7 titanium bar (Ti Grade 7 / UNS R52400) is a palladium-enhanced, commercially pure (CP) titanium alloy specifically engineered for supreme corrosion resistance in aggressive environments. It consists of titanium (≥99%) with a critical addition of 0.12–0.25% palladium (Pd), which fundamentally alters its electrochemical behavior. This palladium modification dramatically improves resistance to reducing acids (e.g., sulfuric, hydrochloric, phosphoric), chloride solutions (including seawater and brines), and crevice/pitting corrosion—scenarios where standard CP grades like Grade 2 would rapidly degrade. While retaining the inherent advantages of titanium—low density (~4.5 g/cm³), high strength-to-weight ratio, excellent weldability, and biocompatibility—Grade 7 exhibits superior performance at elevated temperatures (up to ~400°C/750°F) and in highly oxidizing or acidic conditions. Its passive oxide layer, stabilized by palladium, provides unparalleled protection against chemical attack, making it one of the most corrosion-resistant metallic materials available.

Where is Grade 7 titanium bar used?

Grade 7 titanium bar is extensively used in chemical processing for critical components like valve stems, pump shafts, fasteners, and instrumentation components handling acids, chlorides, or organic solvents. In marine and offshore engineering, it serves in seawater desalination equipment, heat exchanger components, and subsea fastening systems exposed to high-salinity environments. The alloy also excels in pollution control systems (e.g., scrubber components), pharmaceutical manufacturing equipment, and medical implants (e.g., surgical instruments and orthopedic devices) due to its inertness and longevity. Despite its higher initial cost—driven by palladium content—Grade 7 delivers exceptional lifecycle value by minimizing downtime, maintenance, and replacement costs in corrosive service. Its reliability in preventing catastrophic failures ensures safety and efficiency in applications ranging from nuclear waste containment to aerospace fluid systems, justifying its selection as a premium solution for the most demanding corrosion challenges.

大順 is your trusted titanium alloy rod production company. Daxun produces all grades of titanium alloys, including commercially pure titanium series CP, titanium alloy series, titanium nickel alloy, etc. They have reliable performance and provide high performance for your critical applications. In various industries and applications, you can rely on Daxun titanium alloy rods for high strength, high temperature and corrosive environments.

ASTM B348 – Titanium and Titanium Alloy Bars and Billets
ASTM SB348 – Specification for Titanium and Titanium Alloy Bars and Billets
AMS 4921 – Titanium Alloy Bars, Wire, and Forgings
AMS 4902 – Titanium Alloy Bars and Billets

HEAT TREATMENT

When enhanced corrosion resistance and mechanical properties are required, annealing can be performed at 1,200-1,400°F (649-760°C).
DAXUN Grade 7 alloy can be heat treated in a variety of ways:

  1. Anneal: 1,200-1,400°F (649-760°C), 1 to 2 hours, air cool
  2. Stress Relief Anneal: 900-1,100°F (482-593°C), 1 to 4 hours, air cool

HARDNESS

Typical hardness in the annealed condition is Rockwell B 70-80, providing excellent machinability while maintaining superior corrosion resistance.

Forgeability / Formability

Grade 7 titanium alloy bar is forged at 1,650-1,750°F (899-954°C) with a final forging temperature of 1,450°F (788°C). A minimum of 30% reduction is recommended for optimum properties.

Grade 7 alloy bar exhibits good formability in the annealed condition. For severe forming operations such as bending or stretching, these can be performed at temperatures up to 1,200°F (649°C) without affecting mechanical properties. Hot sizing or forming can be accomplished by creep forming in the range of 1,000-1,200°F (538-649°C).

加工性

Grade 7 titanium alloy bar can be machined using austenitic stainless steel machining methods with slow machining speeds, high feeds, rigid tools, and the use of large amounts of non-chlorinated cutting fluids. The palladium content does not significantly affect machinability compared to other CP titanium grades.

溶接性

Grade 7 titanium rod is readily weldable in the annealed condition. Precautions must be taken to prevent contamination with oxygen, nitrogen, and hydrogen. Fusion welding may be performed in an inert gas filled chamber or with inert gas to weld the molten metal and adjacent heated zones, with a tail shield. The palladium addition enhances weld integrity in corrosive environments.

Special Considerations

Grade 7 titanium alloy rod may be contaminated with hydrogen from improper pickling, and with oxygen, nitrogen, and carbon during forging, heat treating, brazing, etc. This contamination may result in a loss of ductility, which may adversely affect notch sensitivity and forming characteristics. The palladium content provides additional protection against corrosion in contaminated conditions.

どのグレードのチタンが最適ですか？

必要なチタン合金のグレードは、取り組んでいるプロジェクトによって異なります。各グレードには異なる利点があるためです。

すべてのグレードのチタン合金は極めて強靭で耐食性に優れており、過酷な環境下でも良好な性能を維持し続けます。

チタン合金の高グレード品（5～12）は、特定の利点を目的として設計された合金である。例えば、グレード12チタン合金は優れた耐熱性を有し、シェルアンドチューブ式熱交換器、油圧配管、化学工業用機器に最適な選択肢となる。

グレード1～4は純チタン合金であり、配管システムやチューブ用に溶接可能で延性のある材料が必要な場合に最適な選択肢です。低グレード品は船舶産業や工業分野で使用されています。

プロジェクトを開始するにあたり、どのグレードのチタン合金が最適かお悩みでしたら、ぜひ当社までご連絡ください。喜んでご支援いたします。

高品位チタンと低品位チタンはどのように異なるのですか？

大迅では、グレード1からグレード12まで幅広いチタン合金グレードを提供しています。

グレード1～4は純チタンであり、それより上のグレードは合金である。

合金グレードは、高い強度重量比で人気がある。

最も一般的に使用されるチタン合金グレードはグレード5です。チタン含有量は依然として高いものの、このグレードは600°F（約315℃）までの高温に耐え、過酷な条件にも耐えられるため、最も信頼性の高いグレードの一つです。

航空宇宙産業や海洋産業などの業界では、耐摩耗性と耐食性に優れていることから、より高品位のグレードが好まれている。

逆に、低品位の鋼材は強度が低いため、主に溶接用として使用される。

各種チタン合金のグレードの違いについて詳しく知りたい方は、本日+86 13382898899までお電話ください。専門家が直接ご説明いたします。

チタンのグレードはコストに影響しますか？

チタンのグレードはコストをわずかに増加させますが、総コストは主に必要なチタンの形状と形態によって決定されます。

At DAXUN, we offer a wide range of titanium products, including plates, tubes, coils and bars. The length, width and quantity of each item you require will affect the amount you pay at checkout.
