UNS S32750 material Characteristic

Sometimes we receive some orders about UNS S32750 material. It’s one kind of Super duplex stainless steel. This material is made of 25% chromium, 4% molybdenum and 7% nickel.  It has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical industry and sub sea equipment.  UNS S2507 duplex steel has strong chloride corrosion resistance, high thermal conductivity and low coefficient of thermal expansion.  The high content of chromium, molybdenum and nitrogen gives it high resistance to patchy corrosion, crack corrosion and general corrosion.

The impact strength of UNS S32750 duplex steel is also very high. It is not suitable for use in a temperature environment higher than 570℃. In such an environment for a long time, its toughness will be reduced.  UNS S32750 duplex steel has integrated many ferritic steel and austenitic steel is the most beneficial properties, because the steel chromium and molybdenum content is very high, so has excellent resistance to corrosion, crevice corrosion and the ability of uniform corrosion, duplex microstructure ensures that the steel has the ability of high resistance to stress corrosion cracking, and the mechanical strength is high.
