国内外模具钢发展现状

Development status of model steels at home and abroad

简要分析了过去、现在乃至今后国内外模具钢(冷作模具钢、热作模具钢和塑料模具钢)发展的基本指导思想及在此指导思想下研发的各种新型模具钢。最后对我国模具钢发展和生产中存在的问题进行了分析并提出了建议。

The basic guiding thought of development of mould steels（ in cold work, hot work and plastic mould steels） in the past, present and future at home and abroad was analyzed as well as some new type mould steels developed under the guide of this thought. The existing problems in development and manufacture of domestic mould steels was also analyzed, and suggestions on which was proposed.
