The ASTM A312 standard covers seamless and straight-seam welded steel pipes for high-temperature and general corrosive service.
ASTM A312 stainless steel pipes offer high yield strength, high tensile strength, and excellent resistance to temperature and pressure.
The most popular steel grades of ASTM A312 include TP304/304L, TP316/316L, TP304H, TP317L, and TP321.
ASTM A312 Seamless Pipe (SMLS) is made from stainless steel billets through hot rolling or cold drawing, with no welding process during manufacturing.
