RS ISO 4957: 2018
Tool steels
Abstract

This document specifies requirements for the following grades of wrought tool steels:
a) non-alloy cold-work tool steels;
b) alloy cold-work tool steels;
c) alloy hot-work tool steels;
d) high-speed tool steels.
If not stated otherwise, this document applies to all types of hot-rolled, forged, cold-drawn or coldrolled
products or products produced by powder metallurgy, which are supplied in one of the surface
and heat-treatment conditions given in 6.2 and Table 1.
NOTE Tables 2, 4, 6 and 8 cover only those steels which have gained certain international importance, which
does not mean, however, that they are available in all industrial countries. In addition, a number of other steels
for tools are specified in regional, national or company standards.
Where the heat resistance of the tools is of particular importance, as for example in the case of tools for
hot forming glass, the material selection is based on ISO 4955.
