Anotácia textu normy ASTM A288-18(2023) :
This specification covers quenched and tempered carbon and alloy steel forgings for magnetic retaining rings for turbine generators. Specimens shall be manufactured by melting process and vacuum degassing. Forgings shall also undergo preliminary machining prior to heat treatment (quenching and tempering) for mechanical properties testing. Steel materials shall conform to tensile and notch toughness requirements, which include tensile strength, yield strength, elongation, reduction of area, and Charpy V-notch impact strength. Heat and product analyses shall be performed as well wherein specimens shall conform to chemical requirements of carbon, manganese, phosphorus, sulfur, nickel, chromium, molybdenum, and vanadium. Nondestructive tests such as magnetic particle test and ultrasonic inspection may also be performed.
