Stainless steel materials and classification

It has been incorporated into various standard stainless steels in the world, nearly 100 types, and with the advancement of science and technology and the development of industry and agriculture, the value of new stainless steels is growing. For famous brands.

Martensitic stainless steel, duplex stainless steel and precipitation hardening stainless steel.

According to the classification of corrosion types

It can be divided into pitting resistance to stress corrosion of stainless steel, stainless steel, stainless steel intergranular corrosion resistance, etc.

According to the classification of function characteristics

It can be divided into free cutting stainless steel, non-magnetic stainless steel, stainless steel, high strength stainless steel at low temperature.

According to the matrix is divided into

1, ferritic stainless steel. Chromium contains 12%~30%. Its corrosion resistance, toughness and weldability with chromium content increases with increasing corrosion resistance chloride stress is superior to other types of stainless steel.

2, austenitic stainless steel. Chromium is more than 18%, still contains about 8% nickel and small amounts of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance, corrosion resistance to various media.

3, Austenitic duplex stainless steel, ferritic. It advantages from austenitic and ferritic stainless steels, and has superplasticity.

4, Martensitic stainless steel. High strength, but poor plasticity and weldability.
