Product description

Duplex stainless steel Grade

Duplex stainless steel is in its solid solution structure ferritic phase and austenite phase about half, the general amount of small phase content also need to reach 30%. When the content of C is low, the content of Cr is 18%~28%, and the content of Ni is 3%~10%. Some steels also contain Mo, Cu, Nb, Ti, N and other alloying elements. This kind of steel has the characteristics of austenitic and ferritic stainless steel, compared with ferrite, higher plasticity, toughness, no brittleness at room temperature, intergranular corrosion resistance and welding performance are significantly improved, but also maintain the 475℃ brittleness of ferritic stainless steel and high thermal conductivity, with superplastic characteristics. Compared with austenitic stainless steel, it has higher strength and resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent corrosion resistance and is also a nickel-saving stainless steel

SAF 2507 offers high compressive strength, impact strength, low coefficient of thermal expansion and high thermal conductivity.

These characteristics are applicable to many structural and mechanical components.

SAF 2507 has high impact strength and is not suitable for prolonged exposure to temperatures higher than 570°F, which may reduce toughness.

Tensile strength: σb≥ 730MPa

Elongation: δ≥20%
