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 1936 was also built using a spot-welded stainless steel hull. Due to its thermal stability, the Bristol Aeroplane Company built the all-stainless steel Bristol 188 high-speed research aircraft, which first flew in 1963. However, the practical problems encountered meant that Concorde employed aluminium alloys. The use of stainless steel in mainstream aircraft is hindered by its excessive weight compared to other materials, such as aluminium. Surgical tools and medical equipment are usually made of stainless steel, because of its durability and ability to be sterilized in an autoclave. In addition, surgical implants such as bone reinforcements and replacements (e.g. hip
