Grade 204Cu
Copper-bearing Cr-Mn austenitic grade with superior deep-draw performance.
Material Overview
Cr-Mn-Cu Austenitic
204Cu is a copper-modified austenitic stainless steel engineered for deep-drawing operations. The added copper improves cold-work hardening behaviour, allowing producers of utensils and sinks to make multi-stage drawn components without intermediate annealing.
