Abstract
The importance and difficulty of selecting tool materials are discussed and a logical system based on numerical property ratings is suggested.
To ensure constant availability of a full range of materials a controlled diversification of steels is proposed, which would conserve strategic elements such as molybdenum.
A number of special materials and coatings are reviewed and some recent developments in tool-steel manufacture are briefly considered.
