Specifications
ASTM A269 TP321 is a specification for seamless or welded austenitic stainless steel tubing, known for its high-temperature stability and corrosion resistance due to the addition of titanium. Key specifications include a composition of 17-19% chromium, 9-12% nickel, and titanium addition for carbide stabilization, which prevents intergranular corrosion at high temperatures. It must be furnished in a heat-treated condition, with mechanical properties including a minimum tensile strength of 515MPa and a minimum elongation of 40%.
