Duplex stainless steel pipe has good welding performance. Compared with ferritic stainless steel and austenitic stainless steel, it is neither like the welding heat-affected zone of ferritic stainless steel. Due to the severe coarsening of crystal grains, the plastic toughness is greatly reduced. It is also not as sensitive to welding hot cracks as austenitic stainless steel.
Austenitic-ferritic duplex stainless steel is a stainless steel in which austenite and ferritic structure each account for about half. In the case of low C content, 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. 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 the 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.
While China's duplex stainless steel is experiencing continuous production growth, its application fields are also expanding. While consolidating and improving the use of duplex stainless steel in major applications such as petrochemicals, in recent years, China's duplex stainless steel has been used in oil and gas transportation and chemical tankers. The fields of manufacturing, nuclear power and construction have been continuously expanded. In petrochemical plants with a variety of reducing, strong oxidizing and high temperature corrosive media containing halide ions, H2S, CO2, etc., duplex stainless steel is especially suitable for solving its pitting, crevice corrosion and stress corrosion cracking problems. The petrochemical industry is still one of the most important application areas of duplex stainless steel.
