DIN 17440 Grade X6Cr17 Heat Treated – Premium Corrosion‑Resistant Stainless Steel

The material X6Cr17, mat. no. 1.4016, is resistant to intercrystalline corrosion in the delivery condition but not in the welded condition. The material is used for wire acc. DIN 17440 : 1996-09. For the application acc. DIN 17440 : 1985-07 (X 6 Cr 17) resp. acc. DIN EN 10088-1,-2,-3 : 1995-08 (X6Cr17) applies: The grade (17 % Cr) is extensively resistant to thinned lyes, weak oxidising acids (e.g. nitric acid), water and steam. It is used as cold rolled sheet for washing machines and kitchen parts, cutlery, coverings, decorative strips, hub caps, in the food industry and the nitric acid industry. The material is good deep drawable and polishable (valid for unwelded parts). In the building industry the steel is applicated for decorative purposes like racks and furniture frames, safes, labels. Basic requirement for an good corrosion resistance is a metallic clean surface. X6Cr17 is used in the cold rolled resp. ground or polished condition.
