Cr12MoV

Description

Cr12MoV是中国标准冷作工具钢。钢的淬透性、淬火回火的硬度、耐磨性、强度均比Cr12高。形状复杂、工作条件繁重下的各种冷冲模具和工具。

Cr12MoV is a Chinese standard cold working tool steel. The hardenability, quenching and tempering hardness, wear resistance and strength of steel are higher than those of Cr12. Various cold stamping dies and tools with complex shape and heavy working conditions.

Features and Application

Cr12MoV模具钢淬透性、淬火回火后的硬度、强度、韧性比CR12高,直径为300~400mm以下的工件可完全淬透,淬火变形小,但高温塑性较差。

Cr12MoV多用于制造截面较大、形状复杂、工作负荷较重的合种模具和工具。如冲孔凹模、切边模、滚边模、钢板等。

Cr12MoV die steel has higher hardenability, hardness, strength and toughness after quenching and tempering than Cr12. Workpieces with diameter less than 300 ~ 400mm can be completely quenched, with small quenching deformation, but poor high-temperature plasticity.

Cr12MoV is mainly used to manufacture hybrid molds and tools with large section, complex shape and heavy workload. Such as punching die, trimming die, edging die, steel plate, etc.
