High Pressure 1.4410 Super Duplex Seamless Tube ASTM A790 UNS S32750 Material
S32750 Super Duplex Seamless Pipe 1.4410 25%Cr Duplex Pren ≥40.0
2507 (UNS S32750) 25% chromium duplex stainless steel
General attributes:
S32750 Super Duplex seamless pipe has higher corrosion resistance and better mechanical properties than duplex stainless steel 2205 (S31803). Commonly used in special chemical environments such as offshore oil platforms (heat exchanger tubes, water treatment and water supply systems, fire protection systems, water spray systems, water stabilization systems), desalination (desalination) equipment (high-pressure pipes in seawater equipment, and seawater pipes) Device. Names S32750, 2507, F53, GB 00Cr25Ni7Mo4N.
Its impact strength is also very high. The S32750 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
