2.1.1 The user's point of view

The choice of steel is made by the user of the extruded part, taking into account mechanical stresses, resistance to wear, corrosion, etc. These functional requirements guide the choice into a range of economically cold-formable grades. These functional requirements guide the choice within a range of economically cold-formable grades.

Obtaining complex geometries or high deformation rates may lead to restrictions on the use of the range of grades...
