Stainless steel 430 (EN 1.4016) with 17% chromium, which is used in washing machine drums, dishwasher interiors and refrigerator exteriors. Type 409 Type EN 1.4003+Nb) is used extensively in the manufacture of automotive exhausts Variants of EN 1.4105 are soft magnetic grades used in injectors, . Martensitic stainless steels offer a wide range of properties and are used as stainless engineering steels, stainless tool steels, creep resisting steels. They fall into 4 categories (with some overlap): Martensitic stainless steels form a family of stainless steels that can be heat treated to provide the adequate level of mechanical properties. The heat treatment typically
Stainless steel on the surface. A final finish can then be applied to achieve the desired aesthetic appearance. Most of the world stainless steel production is produced by the following process Hot rolled coils are pickled in acid solutions to remove the oxide scale on the surface, then subsequently cold rolled (Sendzimir rolling mills), annealed in a protective atmosphere, until the desired thickness and surface finish is obtained. Further operations such as slitting, tube forming, etc. can be carried out in downstream facilities. Hot rolled bars are straightened, then machined to the required tolerance and finish. Wire rod coils are subsequently processed
