X3CrNiCu18-9-4 Steel - Nr.1.4567
Copper-Enhanced Austenitic Stainless Steel for Cold Forming
The addition of copper to the base characteristics of AISI 304 significantly increases cold deformability. It is therefore used for fasteners and in general for cold moulded parts when they are complex and have extreme deformations.
