Tool steels

This document specifies requirements for the following grades of wrought tool steels:

1. non-alloy cold-work tool steels;

2. alloy cold-work tool steels;

3. alloy hot-work tool steels;

4. high-speed tool steels.

If not stated otherwise this document 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 6.2 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.

Frequently Asked Questions about BS EN ISO 4957:2018

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

How can I get involved in the further development of this standard?

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
