Ti-15-3 Titanium Sheet | AMS4914J & STA Processing<\/h1>\n

Direct answer:<\/strong> DAXUN can coordinate the supply of Ti-15-3-3-3 titanium flat products and qualified solution-treatment and aging services through the applicable mill and processors. The work follows the governing aerospace material specification or customer-controlled process. For cold-rolled sheet and strip up to and including 0.125 inch (3.18 mm), the principal current AMS material route is SAE AMS4914J<\/strong>, which covers Ti-15V-3Al-3Cr-3Sn in the solution heat-treated condition. Parts are typically formed while the alloy is still ductile in that condition and then precipitation heat treated to develop the required final strength.[1]<\/p>\n

\"\"<\/p>\n

There is an important product-form boundary. AMS4914J covers sheet and strip, not plate above 3.18 mm. We can review thicker Ti-15-3 flat product and coordinate STA processing, but it must follow a customer material specification, approved drawing, or another explicitly accepted procurement route. It should not be certified as \u201cAMS4914J plate.\u201d<\/p>\n

What Is Ti-15-3-3-3 Titanium?<\/h2>\n

Ti-15-3 is a metastable beta titanium alloy officially designated in AMS4914J as Ti-15V-3Al-3Cr-3Sn. Producer literature may list the last three alloying additions in a different order, but both forms refer to the same UNS R58153 alloy family. After the first identification, this page uses the shorter name Ti-15-3. The purchase order should always retain the exact designation required by the governing specification.<\/p>\n

Its appeal comes from a useful two-stage personality. In the solution-treated condition, the retained beta structure gives the alloy unusually good cold formability for a high-strength titanium alloy. During aging, fine alpha precipitates develop within the beta matrix and raise the strength substantially. That allows a manufacturer to form a complicated sheet-metal part first and strengthen it afterward.[6][7][8]<\/p>\n

TIMET publishes a density of approximately 4.78 g\/cm\u00b3 and a beta-transus range of about 750 to 770 \u00b0C. The same data sheet describes the alloy as cold formable in the solution-treated condition and high strength after aging.[6] These values are useful engineering references, but they are not a substitute for the ordered material specification, heat-specific MTC, or part design allowables.<\/p>\n

The AMS Route: Material Specification, Heat Treatment, and Furnace Control<\/h2>\n

An RFQ that says only \u201cTi-15-3 plate, STA, AMS\u201d is not complete. Several documents can have different jobs in the final purchase route.<\/p>\n

Document<\/th>\nCurrent edition used on this page<\/th>\nWhat it controls<\/th>\n<\/tr>\n<\/thead>\n
SAE AMS4914J<\/td>\nRevised January 2025<\/td>\nCold-rolled Ti-15-3 sheet and strip through 3.18 mm, supplied solution heat treated; the product is commonly formed in this condition and precipitation heat treated afterward[1]<\/td>\n<\/tr>\n
SAE AMS-H-81200D<\/td>\nRevised July 2014<\/td>\nHeat-treatment requirements for titanium and titanium-alloy mill products, including applicable procedures, equipment, and testing provisions when invoked by the material or customer specification[2]<\/td>\n<\/tr>\n
SAE AMS2801D<\/td>\nRevised March 2024<\/td>\nHeat-treatment requirements for titanium and titanium-alloy parts, including processing after forming or other manufacturing operations where the approved route requires it; raw-material heat treatment is addressed separately[3]<\/td>\n<\/tr>\n
SAE AMS2750H<\/td>\nRevised July 2024<\/td>\nPyrometric control for thermal-processing equipment, including sensors, instrumentation, system accuracy tests, and temperature-uniformity surveys[4]<\/td>\n<\/tr>\n
SAE AMS2242H<\/td>\nRevised October 2025<\/td>\nEstablished manufacturing tolerances applicable to corrosion- and heat-resistant steel, iron-alloy, titanium, and titanium-alloy sheet, strip, and plate; the product specification and order determine when it is invoked[5]<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

These documents are complementary, not interchangeable. AMS4914J identifies the alloy, product form, delivery condition, and material acceptance route. AMS-H-81200D or AMS2801D can govern how the heat treatment is performed, depending on whether the work concerns raw material or a fabricated part. AMS2750H controls the furnace measurement system; it does not supply the alloy-specific temperature, time, cooling method, or mechanical acceptance values by itself.<\/p>\n

The purchase order must name the required editions. Legacy aerospace drawings may invoke an older revision, while a new order may require the current edition. The responsible engineering authority must approve any substitution.<\/p>\n

AMS4914J Is Not an STA Plate Specification<\/h2>\n

This point is worth stating plainly because it prevents expensive certification mistakes.<\/p>\n

AMS4914J is titled for cold-rolled sheet and strip in the solution heat-treated condition<\/strong>. Its scope ends at 0.125 inch (3.18 mm). The specification\u2019s application is built around forming in the solution-treated condition and precipitation heat treating afterward.[1] Nippon Steel also notes that AMS4914 requires mechanical-property verification after aging in addition to chemistry and solution-treated properties.[7]<\/p>\n

That does not create a separate, unlimited-thickness \u201cAMS4914 STA plate\u201d category. If the finished item is physically aged after forming, the order should state:<\/p>\n
