ASTM A266/A266M-24

Annotation of standard text ASTM A266/A266M-24 :

This specification covers four grades of carbon steel forgings for boiler and pressure vessel components, and associated equipment. Materials shall be manufactured by melting process and hot-worked forging. Heat and product analyses shall be performed wherein forgings shall conform to chemical requirements for carbon, manganese, phosphorus, sulphur, and silicon. Mechanical properties such as tensile strength, yield strength, elongation, and reduction of area shall be inspected as well. The requirements for annealed, normalized, or normalized and tempered steel forgings, and that for quenched and tempered steel forgings have been specified separately.
