Stainless steel plate is an alloy steel with smooth surface, high weldability, corrosion resistance,
polishability,heat resistance, corrosion resistance and other characteristics. It is widely used in various
industries and is an important material in modern industry. Stainless steel is divided into austenitic stainless
steel,ferritic stainless steel, martensitic stainless steel, and duplex stainless steel according to the structure
state.
Ferritic Stainless Steel: It contains 15% to 30% chromium and has a body-centered cubic crystal structure.
This type of steel generally does not contain nickel, and sometimes contains a small amount of Mo, Ti, Nb
and other elements. This type of steel has the characteristics of large thermal conductivity, small expansion
coefficient, good oxidation resistance, and excellent stress corrosion resistance.
Austenitic Stainless Steel: stainless steel with an austenitic structure at room temperature. Steel contains
Cr≈18%, Ni≈8%-25% and C≈0.1%. Steel has high toughness and plasticity, but low strength.
Martensitic Stainless Steel: A steel whose mechanical properties can be adjusted by heat treatment.
It has different strength and toughness at different tempering temperatures.
Duplex Stainless Steel: Austenitic and ferrite each account for about half of the structure.
When the C content is low, the Cr content is 18% to 28%, and the Ni content is 3% to 10%.
Some steels also contain alloying elements such as Mo, Cu, Si, Nb, Ti, and N. This type of steel has the
characteristics of austenitic and ferritic stainless steel
