1 Scope

This technical report provides a uniform system for grouping of materials for welding purposes. It may also apply for other purposes as heat treatment, forming, non destructive testing, ...

This technical report covers grouping systems for the following standardized materials :

steel;

aluminium and its alloys;

nickel and its alloys;

copper and its alloys;

titanium and its alloys;

zirconium and its alloys;

cast irons.

This technical report is part of a series of standards. Annex A gives details of this series of standards.

2 Grouping system for steels

Steels are grouped as shown in Table 1. Only those elements that are specified in material standards or specifications shall be considered. The figures given in group 1 and 11 are referring to the ladle analysis of the materials. The figures given in groups 4 to 10 are based on the element content used in the designation of the alloys.
