Anotácia textu normy ASTM A592/A592M-24 :

ASTM A592/A592M-04 covers the standard specification for high-strength quenched and tempered low-alloy steel forged fittings and parts used for pressure vessels. The steel shall be made by a melting process and shall be fully killed and fine grained. After forging and before reheating, the forgings shall be cooled to provide substantially complete transformation of austenite. Samples for mechanical test specimens shall be removed after the quenching and tempering heat treatment. The test specimens may be machined from a production forging or from special forged blocks suitably worked and heat treated with the production forgings. Such special blocks shall be obtained from an ingot, slab, or billet from the same heat as the forgings they represent and shall be reduced by forging in a manner similar to that for the products to be represented. The specimens shall undergo tension and Charpy V-notch impact tests.
