AMS 4911 is the aerospace material specification for annealed Ti-6Al-4V (Grade 5) titanium sheet, strip and plate, with a composition similar to UNS R56400. It covers flat product up through 4.000 inches (101.60 mm) thick, fixes the annealed condition and mechanical properties, and adds aerospace-level testing such as ultrasonic inspection of plate. Ordering flat product

When a drawing calls out an ASTM standard, order it to the commercial specification for that form: standard, grade, form, size, condition and EN 10204 3.1 certificate belong on the same line of your RFQ. When a drawing calls out AMS, the part is aerospace-grade: it needs a defined heat-treat condition, tighter inspection, and traceability

ASTM B381 is a material specification for titanium and titanium-alloy forgings. It defines covered grades and their chemical and mechanical requirements for products such as discs, rings, blocks and drawing-based forged parts. A complete forging RFQ also needs the grade, condition, drawing, dimensions, machining allowance, inspection scope and document requirements. Grade 12 weld neck flange

ASTM B338 is the standard specification for seamless and welded titanium and titanium alloy tubes used in condensers and heat exchangers. It is a tube standard, not a pipe standard. Titanium pipe is normally specified to ASTM B861 for seamless pipe or ASTM B862 for welded pipe. What ASTM B338 covers Beiyu Titanium supplies ASTM
