ASTM A312 /A312M ASME SA312 Covers seamless, straight-seam welded, and heavily cold worked welded austenitic stainless-steel pipe intended for high-temperature and general corrosive service. ASTM A312 /A312M ASME SA312 Grades TP304, TP304L, TP304H, TP309S, TP309H, TP310S, TP310H,
Stainless steel pipe ASTM A312 has 4 main grades TP304/304L, TP316/316L. TP304/TP304L and TP347 are included in ASME pressure vessel code and the Chemical Plant and Refinery Piping Code, These steel tubes are safe to be used in temperatures as low as −425 °F [−250 °C] without impact tests qualification.
1.5 Grades TP321 and TP321H have lower strength requirements for pipe manufactured by the seamless process in nominal wall thicknesses greater than ³/ 8 in. [9.5 mm]. 1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets.
