1. Properties
A distinction is made between two types of steel properties: those related to the end use of the product, i.e. service life, and those related to the processing of the products, since they can rarely be used without operations such as forming or joining. These two types of properties are sometimes contradictory: for example, high strength, which improves service life, is at odds with the high ductility required for forming. The trade-offs between these requirements form the basis for adapting grades to the application.
1.1 Application properties
The properties of use are represented by the characteristics that ensure the service life of constructions and objects:
the most important is yield strength R ...

Codes
CODAP is the French pressure equipment code, available from CETIM in Senlis. However, there is now a standardized European code in 4 parts:
NF EN 12952 Water-tube boilers ;
NF EN 12953 Fire tube boilers ;
NF EN 13445 Unfired pressure vessels ;
NF EN 13480 Industrial piping.
