高耐磨铸造冷作模具钢是在传统Ｃｒ１２类钢的基础上，通过合金化、变质处理及随后热处理获得的具有粒状碳化物的新型铸造模具钢。从根本上解决了传统Ｃｒ１２类钢铸造模具强韧性低的问题。本文测试了该高耐磨铸造冷作模具钢的显微组织及力学性能，并在农机链条制造中进行...
High-wear-resistant cast cold work die steel is a new type of cast die steel with granular carbides obtained by alloying, metamorphic treatment and subsequent heat treatment on the basis of conventional Cr12-type steel. From a fundamental solution to the traditional Cr12 steel casting mold low toughness problems. This paper tests the high wear-resistant cast cold work die steel microstructure and mechanical properties, and in the agricultural chain manufacturing ...
