    Product Tags

    The DSS, which is short for the Duplex Stainless Steel, is a group of stainless steel with characteristics of around half of austenitic and half ferritic in microstructure. Compared with ferrite stainless steel, it has higher plasticity and ductility, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance, while still maintaining brittleness, high thermal conductivity, and superplasticity as ferrite stainless steel. Compared with austenitic stainless steel, DSS 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.
