ISO 683-3:2014
Heat-treatable steels, alloy steels and free-cutting steels — Part 3: Case-hardening steels
ISO 683-3:2014 specifies the technical delivery requirements for semi-finished products, hot formed, e.g. blooms, billets, slabs, for bars, wire rod, finished flat products, and hammer or drop forgings manufactured from case-hardening non-alloy or alloy steels and supplied in one of the heat-treatment conditions given for the different types of products and in one of the surface conditions given. The steels are, in general, intended for the manufacture of case-hardened machine parts.
