Duplex is a powerful austenitic and ferritic dual-microstructure grade. The duplex plate has a chemical composition of carbon, manganese, silicon, phosphorous, sulfur, chromium, molybdenum, nickel, nitrogen, and copper. Duplex stainless steel plate has excellent corrosion resistance and tolerance in harsh environments. The plates are tolerant to crevice corrosion and pitting by chlorides. The s2205 is a common grade of the duplex grade. The duplex plate supplier subject the plates to harsh conditions and has a temperature limit below 600 degrees f. These plates can be easily welded following standard procedures.
The duplex plate material grade has excellent mechanical properties. This material has an ultimate tensile strength of 95ksi with a minimum yield strength of 65ksi. The duplex plate suppliers supply these plates with a hardness of 31 rockwell c max. These plates have a density of 7800 kg/m3 with an elastic modulus of 190gpa. The common duplex stainless steel plate application in marine systems. These plates are also common in processing equipment, chemical processing, oil and gas exploration, paper machines, etc. The duplex steel plate has a superior surface finish and tolerances.
