S32750 / F53 Duplex Stainless Steel Seamless Pipe For Chemical Processing
S32750 / F53 Duplex Stainless Steel Seamless Pipe For Chemical Processing
S32750 / F53 Super Duplex Stainless Steel seamless Pipe 25%Cr Pren ≥40.0
2507 (UNS S32750) 25% chromium duplex stainless steel
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.
Its impact strength is also very high. The 2507 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 chemical composition is shown below
