Scope

This International standard covers the grades of wrought tool steels listed in tables 2, 4, 6 and 8, namely: a) unalloyed cold-work tool steels (see table 2); b) alloyed cold-work tool steels (see table 4); c) alloyed hot-work tool steels (see table 6); d) high-speed steels (see table 8). If not stated otherwise, this International Standard applies to all types of hot-rolled, forged, cold-drawn or cold-rolled products or products produced by powder metallurgy which are supplied in one of the surface and heat-treatment conditions given in 6.1.2 and Table 1.
