Spotted an interesting article on Tool steels over at a new blog to me.
Steels used for making tools, punches, and dies are perhaps the hardest, the strongest, and toughest steels used in industry. It is obvious that tools used for working steels and other metals must be stronger and harder than the steels or material they cut or form.
The metallurgical characteristics of various compositions of tool steels are extremely complex. There are hundreds of different makes and types of tool steels available and each may have a specific composition and end use.
In the United States, the Society of Automotive Engineers, in cooperation with the American Iron and Steel Institute, has established a classification system which relates to the use of the material and its composition or type of heat treatment.
