Identifying the Cause of Tool and Die Failure

Steels used for tools and dies differ from most other steels in several aspects. First they are used in the manufacture of other products by a variety of forming processes. Second, tools and dies are generally used at higher hardnesses than most other steel products; 58 to 68 Rockwell C is a typical range. Dies for plastic molding or hot working are usually used at lower hardnesses, typically from 30 to 55 Rockwell C.
