Super Duplex 32750
| UNS S32750 | ASTM/ASME A240 / F55 | Werkstoff 1.4410
Fortune Ferroment Inc 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.
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.
