This has just evolved in the 1970s and is one of the second generation of duplex stainless steel The 255 / S32550 duplex stainless steel, with good mechanical properties, especially wear resistance is better than the general austenitic stainless steel, is the ideal material for seawater environment for the ship with a screw propeller, shaft, submarine seals Wait. The higher chrome, molybdenum and nitrogen contents have a high resistance to erosion, crevice corrosion and general corrosion, and it also has strong resistance to chloride corrosion, higher thermal conductivity and lower thermal expansion Coefficient, can be widely applied to petroleum, chemical, natural gas, pulp, paper and other fields.
