Introduction
Stainless steel is the abbreviation for stainless steel and acid-resistant steel. It is called stainless steel that can resist weak corrosive media such as air, steam and water, or stainless steel. It has chemical resistance to chemical corrosive media (acid, alkali, salt, etc.). Corrosive steel is called acid-resistant steel.
Stainless steel is often divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel and precipitation hardening stainless steel according to the state of organization. In addition, it can be divided into chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel according to the composition.
Austenitic-ferritic duplex stainless steel
It has the advantages of austenitic and ferritic stainless steel, and has superplasticity. Austenitic and ferritic structures each account for about half of stainless steel. In the case of low carbon content, the content of chromium (Cr) is between 18% and 28%, and the content of nickel (Ni) is between 3% and 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. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance, while still maintaining iron The 475℃ brittleness, high thermal conductivity, and superplasticity of element stainless steel.
Compared with austenitic stainless steel, it has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel-saving stainless steel.
