Die Annotation des Normtextes ASTM A542/A542M-25 :

This specification covers pressure vessel plates, alloy steel, quenched-and-tempered, chromium-molybdenum, and chromium-molybdenum-vanadium. As a steel making practice, the steel shall be killed and shall conform to specified fine austenitic grain size requirements. Plate types A, B, C, D, and E shall be heat treated by heating to a suitable austenitizing temperature, holding for a sufficient period of time to attain uniform temperature throughout the thickness, and quenching in a suitable liquid medium by spraying or immersion. The steel shall conform to the required chemical compositions. The required mechanical properties that include tension test requirements and notch toughness requirements are presented in details.
