Heat-treatable steels, alloy steels and free-cutting steels - Part 3: Case-hardening steels

This document specifies the technical delivery requirements for —    semi-finished products, hot formed (e.g. blooms, billets, slabs) (see NOTE 1), —    bars (see NOTE 1), —    wire rod, —    finished flat products, and —    hammer or drop forgings (see NOTE 1) manufactured from the case-hardening non-alloy or alloy steels listed in Table 3 and supplied in one of the heat-treatment conditions given for the different types of products in Table 1 and in one of the surface conditions given in Table 2. The steels are, in general, intended for the manufacture of case-hardened machine parts. NOTE 1   Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammerforged bars are covered under semi-finished products or bars and not under the term “hammer and drop forgings”. NOTE 2   For International Standards relating to steels conforming with the requirements for the chemical composition in Table 3, however, supplied in other product forms or treatment conditions than given above or intended for special applications, and for other related International Standards, see the Bibliography.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
