Duplex stainless steel coil & sheet is a stainless steel material with a special organizational structure and properties. Firstly, duplex stainless steel coil & sheet consists of an austenitic phase and a ferritic phase, the proportion of which usually ranges between 30% and 70%. This duplex structure makes duplex stainless steel have the dual properties of austenite and ferrite, combining the advantages of both. Secondly, duplex stainless steel coil & sheet has a high strength, its yield strength can reach 400-550MPa, twice as much as ordinary stainless steel. In addition, duplex stainless steel coil & sheet has high strength while also maintaining good toughness. This gives it good resistance to deformation and fatigue under shock loading and vibration. In addition, duplex stainless steel coils & sheets have excellent corrosion resistance and good weld-ability.
