Grade 38 Titanium Alloy Sheet

INTRODUCTION
Grade 38 Titanium alloy is a high strength, high ductility, titanium alloy available in a variety of product forms, including cold-rolled coil or sheet. Grade 38 Titanium alloy is an alpha-beta titanium alloy that uses iron and vanadium as beta stabilizers as well as aluminum as an alpha stabilizer. The lower aluminum and vanadium contents and higher oxygen and iron contents give Grade 38 alloy a unique combination of ductility and tensile strength. The combination of strength and ductility found in grade 38 titanium alloy makes it useful for titanium applications that require cold forming, such as roll-forming and bending, while still providing superior strength compared to low alloy grades of titanium. Grade 38 Titanium alloy in the cold-rolled titanium coil or sheet product forms provides advantages that come from continuous processing that are not available in pack-rolled sheets. For example, the Grade 38 Titanium alloy cold-rolled product has better gauge tolerance and surface finish than a pack-rolled sheet and is available in lengths ranging from cut sheet to coil. Coil-length products are generally not available in other titanium alloys with tensile strengths exceeding 130 ksi (896 MPa) and ductility exceeding 10% elongation.

SPECIFICATIONS AND CERTIFICATES
AMS 6946B – Cold-rolled sheet and coil and hot-rolled sheet and plate in the mill annealed condition. Titanium grade 38 alloy by ASTM and covered by ASTM specifications B265, B338, B348, B381 and B861. Titanium grade 38 alloy has been Board Approved for use in the ASME Boiler and PV Code to 650°F, making Titanium grade 38 alloy the highest temperature ASME code approved titanium alloy in the B&PV code. ASME Boiler Code Case 2532-2 states that Titanium grade 38 alloy can be used for parts requiring strength up to 700°F (371°C). Titanium grade 38 alloy can be welded using ERTi-38 weld wire, which is produced in accordance with AWS 5.16/A5.16M. Additional industry and customer specifications are being developed.

PRODUCT FORMS
Titanium grade 38 alloy is available in a variety of titanium product forms, including sheet, coil, strip, Precision Rolled Strip, foil, plate, seamless tube, shapes and rectangles, ingot, and castings.

FORMABILITY
Titanium grade 38 alloy can be both hot and cold worked. The excellent ductility permits forming at room temperature. The material produced by AMS 6946 routinely meets at least a 3T bend factor.

WELDABILITY
Titanium grade 38 alloy is easily welded in the annealed condition using methods typically applied to titanium, such as TIG, MIG, EB, and plasma. Precautions must be taken to prevent oxygen, nitrogen, and hydrogen contamination. Fusion welding can be done in inert gas-filled chambers or using inert gas shielding of the molten metal and the adjacent heated zones. Spot, seam, and flash welding can be performed without resorting to protective atmospheres.

CORROSION RESISTANCE
LINKUN has evaluated the corrosion resistance of Titanium grade 38 alloy in a variety of media. Titanium grade 38 alloy performs similarly to Ti-6Al-4V (6-4 titanium) and Ti-3Al-2.5V (3-2.5 titanium) in marine environments and many media of the chemical process industry.

SUPERPLASTIC FORMABILITY
Titanium grade 38 alloy coil or sheet can be processed so that it has good superplastic formability at 1425ºF – 1650°F (774ºC – 899ºC).

SPECIAL PRECAUTIONS
Titanium grade 38 alloy can be subject to excessive contamination by hydrogen during improper heat treatment or pickling and by oxygen, nitrogen, and carbon pickup during forging, heat treating, brazing, etc. This contamination could adversely affect mechanical properties and formability.

POTENTIAL APPLICATIONS
The unique combination of high tensile strength and high ductility of Titanium grade 38 alloy makes it a potential candidate for a wide variety of aerospace, defense, or industry titanium applications. High ductility is beneficial when bending or cold drawing is required.
Good hot workability combined with high strength makes Titanium grade 38 alloy a candidate for near-net shape forgings. The availability of Titanium grade 38 alloy cold-rolled titanium sheet and coil in long lengths facilitates its use in manufacturing methods such as roll forming and may allow structures to be designed with fewer joints and fasteners. The tight gauge tolerance of Titanium grade 38 alloy cold-rolled titanium sheet and coil compared to pack-rolled sheet offers opportunities for weight reduction through the use of nominally lighter gauge products. The excellent surface finish and corrosion resistance make Titanium grade 38 alloy sheet and coil a candidate for use in an uncoated condition.
