Do you know the eight common metals？——Stainless Steel

Stainless steel is an alloy made of chromium, nickel and other metal elements. The non rusting characteristic of chromium comes from the composition of chromium in the alloy. Chromium forms a strong and self repairing chromium oxide film on the surface of the alloy, which is invisible to the naked eye. The ratio of stainless steel to nickel we usually mention is usually 18:10. The term "stainless steel" not only refers to one kind of stainless steel, but also represents more than one hundred kinds of industrial stainless steel. Each kind of stainless steel developed has good performance in its specific application field.

At the beginning of the 20th century, stainless steel was introduced into the field of product design. Designers developed many new products around its toughness and corrosion resistance, involving many areas that had never been involved before. this series of design attempts is very revolutionary: for example, the equipment that can be used again after disinfection is first appeared in the medical industry.

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

Material characteristics: health care, anti-corrosion, fine surface treatment, high rigidity, molding by various processing technologies, and difficult cold processing.

Typical use: austenitic stainless steel is the most suitable coloring material in the common primary color stainless steel, which can obtain satisfactory color appearance and shape. Austenitic stainless steel is mainly used in decorative building materials, household products, industrial pipes and building structures; martensitic stainless steel is mainly used to make knives and turbine blades; ferritic stainless steel has corrosion resistance, mainly used in durable washing machines and boiler parts; composite stainless steel has stronger corrosion resistance, so it is often used in corrosive environment.
