1. Steel grades for mechanical engineering

Table 1 presents a non-exhaustive list of steel grades for use in welded mechanical engineering, in the form of a classification based on ISO/TR 15608.

The presentation of the nuances and the normative reference allow you to find out quickly :

• the type of product involved (flat products, sections, bars, welded or non-welded tubes, forged, cast);

• the reference metallurgical state;

• the product's usual destination ;

• guaranteed minimum yield strength at room temperature ;

• guaranteed mechanical properties at elevated temperatures;

• the temperature for which a breaking energy of 27 J (average value...
