Mechanical properties:
Hardness: Annealing, 255~207HB, indentation diameter 3.8~4.2mm; Quenching, ≥60HRC cr12mov The hardenability, hardness, strength and toughness after quenching and tempering are higher than CR12, and the work with a diameter of 300-400mm or less can be completed Hardenable, small quenching deformation, but poor high temperature plasticity. cr12mov plates are mostly used to manufacture composite molds and tools with large cross-sections, complex shapes and heavy workloads.
