Properties and heat treatment of new cold-working die steels

The development survey and trend of cold-working die steels both at home and abroad were introduced,and the properties and heat-treatment of the new cold-working die steels were expounded in detail,then the future development prospect of the die steels in our country were given.The smelting technology of the die steels should be improved to guarantee the property requirements,and the material series of die should be developed and perfected.Meanwhile,the heat treatment technology should be selected accurately,and the cold and hot working process should be improved to enhance the product quality and die life.
