Super Duplex S32750

We are a stockholder of the 32750 duplex alloys in sheet, plate, and round bar with the added capability of cutting processes to meet requirements across a number of industries. Inconel-625 (1)

The following are the properties of 32750 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.
