A wear-test programme carried out using a newly developed hot-work tool-wear simulation technique is described. Recently developed cast die steels containing coarse carbide dispersions have been assessed by comparison with orthodox hotwork steels. The new materials showed favourable wear properties under hotworking conditions. The relative wear resistances obtained for the materials Show good agreement with the results of previous hot-forging wear tests. Qualitative results from associated wear-surface observations and tool-workpiece compatibility studies are discussed to highlight the role of the technique in the overall assessment of a new tool material.
