ASTM A312 Specifications

ASTM A312 specification covers seamless pipe and welded pipe for austenitic stainless steel. These high performance austenitic stainless steels have a fully austenitic microstructure in the quench annealed condition. These grades are sometime alloyed with nitrogen to improve strength or with sulphur to improve machinability. 904L was originally developed to withstand environments involving dilute sulphuric acid and it is one of the few stainless steels that, at temperatures up to 35°C, provides full resistance. This is mainly due to the high contents of chromium, nickel, molybdenum and nitrogen
