S32750 / 1.4410 Super Duplex Stainless Steel Pipe , Seamless Steel Tube
S32750 / 1.4410 Super Duplex Stainless Steel Seamless Pipe Pren ≥40.0
2507 (UNS S32750) 25% chromium duplex stainless steel
General attributes:
S32750 / 1.4410 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.
Its impact strength is also very high. The S32750 / 1.4410 alloy is not suitable for use at temperatures higher than 570 ° C. If it is exposed to such an environment for a long time, its toughness will decrease. Its mechanical properties is shown below
