ASTM A623-22

Die Annotation des Normtextes ASTM A623-22 :

This specification covers a group of common requirements which shall apply to tin mill products. The steel shall be made by the open-hearth, electric-furnace, or basic-oxygen process. The steel shall conform to specified chemical composition requirements. Rockwell 30T hardness test shall be done to the plates. This test forms the basis for a system of temper designation. The mechanical properties of continuously annealed plate and batch annealed plate of the same Rockwell 30T temper designation are not identical. It is important to keep in mind, that the Rockwell 30T test does not measure all various factors which contribute to the fabrication characteristics of the plate.
