碳素钢【SK7钢带】X精密冲压件硬质钢带
SK7 is 0.6 carbon, high carbon steel belt, used after quench hardening, SK7 excellent wear resistance, and the price is cheaper tool steels. Suitable for sliding parts need high hardness of components and parts of cold work dies. Sk7 materials commonly used in need of elastic parts, stamping features (SPCC) about the same, with strong hardness and rebound slightly, usually stamping again after heat treatment, in order to achieve the required hardness and elasticity
SK7是含碳量0.6的高碳钢带,淬火硬化后使用,SK7耐磨损性X良,且为价格较便宜的工具钢。适用于有滑动部分需要高硬度的零件及制作冷作模具零件。sk7材料常用于需弹性的零件上,冲压特性同spcc差不多,硬度和回弹稍强,通常冲压后再热处理,以达到所需硬度及弹性。
SK7碳素工具钢执行标准:JIS
