ASTM A727/A727M-14(2019)

Anotácia textu normy ASTM A727/A727M-14(2019) :

This specification covers forged carbon steel piping components intended primarily for service in pressure piping systems from a specific temperature range where inherent notch toughness is desired, but where notch toughness testing is not required. Included are forged or ring-rolled flanges, forged fittings, and valves made to specified dimensions. The steel shall be made by one or more of the following processes: open-hearth, basic-oxygen, or electric-furnace, and shall be fully killed, fine-grain practice. Following plastic working, the forgings shall be heat treated by normalizing, or normalizing and tempering, or quenching and tempering. The forgings shall be subjected to tension, hardness, and hydrostatic tests.
