首钢特殊钢公司和华中工学院共同研制的易切削精密模具钢最近通过了部级技术鉴定。这一新钢种具有机械加工性能好、空冷淬硬、淬火变形小、镜面抛光性能好等特点。它适用于制造塑料模、胶木模、瓷品模、橡胶模,也可用来制造薄板精冲模。它的研制成功,符合我国国情,具有独创性,为我国填补了易切削模具钢的空白。
Shougang Special Steel Company and Huazhong Institute of Technology jointly developed by cutting precision mold steel recently passed the ministerial technical appraisal. This new type of steel has good machinability, air-cooled hardened, small quenching deformation, mirror polishing performance and so on. It is suitable for the manufacture of plastic mold, bakelite mold, porcelain mold, rubber mold, can also be used to manufacture thin sheet metal die. Its successful development, in line with China’s national conditions, with originality, for our country to fill the blank cutting die steel.
