　　ASTM A727/A727M-2014

　　中文名称：具有内在切口韧性的管道部件用碳素钢锻件规格

　　英文名称：Standard Specification for Carbon Steel Forgings for Piping Components with Inherent Notch Toughness

　　原文名称：Standard Specification for Carbon Steel Forgings for Piping Components with Inherent Notch Toughness

　　范 围：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.
