1.4570 - Austenitic stainless steel / X6CrNiCuS18-9-2 / AISI 303 Cu
Description
Material 1.4570 (X6CrNiCuS18-9-2 / AISI 303 Cu) – austenitic stainless steel Properties and Applications
The material 1.4570, known as X6CrNiCuS18-9-2 and commercially referred to as AISI 303 Cu, belongs to the group of austenitic stainless steels. It offers excellent corrosion resistance, good machinability, and increased strength due to its copper content. Typical applications include use in mechanical engineering, fastening elements, decorative components, and food industry equipment, where both corrosion resistance and efficient processing are essential. The addition of sulphur and copper ensures improved chip-breaking behaviour, making the alloy especially suitable for the production of precision turned parts.
