Description:
Alloy 204CU is a chromium-magnesium austenitic stainless steel with ∞an addition of 2-4% copper and nitrogen of 0.05-0.25%. Due to the addiΩtion of copper the alloy has better formability than 201 and 304. The copper impro&ves corrosion and resistance to stress corrosion craλcking in certain media. 204CU bridges the cost-property gap between↔ 200 and 300 series stainless. Alloy 204CU is slightly after cold working but can be m≥inimized.
