Description

ASTM A312 is the standard specification issued by the American Society for Testing and Materials (ASTM) for seamless, straight-seam welded, and heavily cold-worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service.

It covers grades such as TP304, TP304L, TP316, and TP316L, ensuring excellent resistance to intergranular corrosion and oxidation scaling. Choosing ASTM A312 certified material guarantees dimensional accuracy, mechanical integrity, and long-term reliability.
