Product Details

2507 (UNS S32750) duplex stainless steel has strong strength and corrosion resistance, which is mainly used in chemical processing, petrochemical industry and subsea equipment. It has strong chloride corrosion resistance, high thermal conductivity and low coefficient of thermal expansion. The high content of chromium, molybdenum and nitrogen makes it highly resistant to patchy, crevice and general corrosion. Its impact strength is also very high,2507 alloy is not suitable for use in a temperature environment higher than 570℃, long-term in such an environment, its toughness will be reduced.
