Note 1: When the impact test criterion for a low-temperature service would be 15 ft·lbf [20 J] energy absorption or 15 mils [0.38 mm] lateral expansion, some of the austenitic stainless steel grades covered by this specification are accepted by certain pressure vessel or piping codes without the necessity of making the actual test.
approved in 1948. Last previous edition approved in 2016 as A312/A312M – 16. DOI: 10.1520/A0312_A0312M-16A. 2 For ASME Boiler and Pressure Vessel Code applications see related Specifi-cation SA-312 in Section II of that Code. 3 For referenced ASTM
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.
