标准摘要
[中文适用范围]: 本标准适用于冷轧碳钢板及相应的硬度要求。 它适用于表面至关重要的应用。 以下为常见硬度范围(见 6.6): ——CRH-50:洛氏 B 50 至 70; ——CRH-60:洛氏B 60至80; ——CRH-70:洛氏B 70至90; ——CRH-NN:任何 20 个点的洛氏 B 范围,最高可达 HRB 90(将显示指定范围的指定最小值)。 注:经供需双方协议,可规定洛氏硬度范围小于 20 点。 本国际标准不涵盖商业质量或绘图质量(涵盖在 [外文原描述]: ISO 5954:2014 applies to cold-reduced carbon steel sheet and corresponding hardness requirements. It is suitable for applications where the surface is of prime importance. The following are common hardness ranges (see 6.6): CRH-50: Rockwell B 50 to 70; CRH-60: Rockwell B 60 to 80; CRH-70: Rockwell B 70 to 90; CRH-NN: Any Rockwell B range of 20 points up to and including HRB 90 maximum (designated minimum of specified range will be shown).
