ICS Code (Tool steels): 77.140.35
scope:

This International Standard covers 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 International Standard applies to all types of hot-rolled, forged, cold-drawn or cold-rolled products which are supplied in one of the surface and heat-treatment conditions.

Products according to this International Standard may be produced by powder metallurgy.

NOTE 1 The 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.

NOTE 2 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 should be based on ISO 4955 or ISO 9722.

In addition to this International Standard, the general technical delivery requirements of ISO 404 are applicable.
