ASTM A790 1.4410 S32750 Duplex Stainless Steel Pipe Polished finished
1.4410 / S32750 Duplex Stainless Steel Tube 2507 Welded Tube Anti Corrosion
1.4410 / S32750 Super Duplex Stainless Steel tube 2507 Welded tube Pren ≥40.0
2507 (UNS S32750) 25% chromium duplex stainless steel
Mechanical properties
| Tensile strength: σb≥730Mpa |
| Elongation: δ≥15% |
General attributes:
S32750 Super Duplex stainless steel pipe has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical and subsea equipment. It has strong resistance to chloride corrosion, higher thermal conductivity and lower coefficient of thermal expansion. Higher chromium, molybdenum and nitrogen content it has a high resistance to pitting, crevice corrosion and general corrosion.
