Material Characteristics And Typical Uses Of Stainless Steel

May 24 2023

Stainless steel is an alloy made by incorporating chromium, nickel and other metal elements into steel. Its non-rusting property is derived from the chromium in the alloy. Chromium forms a strong, self-repairing chromium oxide film on the surface of the alloy, which is invisible to our naked eyes. The ratio of stainless steel and nickel that we usually mention 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 raw material. Designers have developed many new products around its toughness and corrosion resistance, involving many fields that have never been involved before. This series of design attempts are very revolutionary: for example, equipment that can be reused after disinfection appears in the medical industry for the first time.

Stainless steel is divided into four main types: austenite, ferrite, ferrite-austenite (composite), and martensite. The stainless steel used in household products is basically austenitic.

Material characteristics:

health care, anti-corrosion, fine surface treatment, high rigidity, can be formed by various processing techniques, and it is difficult to perform cold processing.

Typical use:

Austenitic stainless steel is mainly used in household goods, industrial pipes and building structures;

Martensitic stainless steel is mainly used to make knives and turbine blades;

Ferritic stainless steel is anti-corrosive and is mainly used in durable washing machines and Among boiler parts;

composite stainless steel has stronger corrosion resistance, so it is often used in corrosive environments.
