Our stock of Super Duplex 32760 can be supplied in sheet, plate, or bar forms, cut to specific requirements and comes with the Jain Steels Metal quality certification.

The following are the properties of S32760 Super Duplex:
 Ferritic-austenitic stainless steel.
 Excellent corrosion resistance against general corrosion, stress corrosion cracking, corrosion fatigue, pitting, crevice and erosion corrosion and possessing very high mechanical strength properties.
 Good weldability, post weld heat treatment not necessary.
 Max. Temperature for long periods of service: 280°C (536°F) / (300°C/572°F possible for short periods).
 Surface condition for optimum corrosion resistance: pickled or machined.

Application
Components in offshore, waste water, sea water desalination and chemical plants with aggressive chloride-containing media e.g. heat exchangers, separator parts, compressor and pump components, turbine blades.
