2B HL NO.4 Stainless Steel Coil Cold Rolled 0.5mm Building Materials
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.
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
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.
