Stainless steel is an alloy made by incorporating chromium, nickel and other metal elements into the steel. Its non-rusting property is derived from the chromium component of the alloy. The chromium forms a firm, self-repairing chrome oxide film on the surface of the alloy. This film is invisible to the naked eye. The ratio of stainless steel to nickel we usually refer to is generally 18:10.
At the beginning of the 20th century, stainless steel began to be introduced into the field of product design as a talented person. Designers have developed a number of new ones around its toughness and corrosion resistance that have involved many areas that have never been involved before. This series of design attempts is very revolutionary: for example, equipment that can be reused after disinfection is first seen in the medical industry.
Stainless steel is divided into four main types: austenite, ferrite, ferrite-austenite (composite), martensite. The stainless steel used in household products is basically austenite.
Material characteristics: health care, anti-corrosion, fine surface treatment, high rigidity, can be formed by various processing techniques, and difficult to carry out cold processing.
Typical applications: austenitic stainless steel is mainly used in household products, industrial pipes and building structures; martensitic stainless steel is mainly used to make tools and turbine blades; ferritic stainless steel is corrosion-resistant, mainly used in durable washing machines and In boiler parts; composite stainless steel is more resistant to corrosion and is often used in aggressive environments.
