S32760 Material Properties
S32760 (F55), X2CrNiMoCuWN 25.7.4, German standard 1.4501, strong strength and corrosion resistance, mainly used in chemical processing, petrochemical and subsea equipment. It has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient. Higher chromium, molybdenum and nitrogen content, it has high resistance to pitting, crevice corrosion and general corrosion.
Alloy S32760 is a super duplex stainless steel supplied in the hot worked and solution annealed condition. As a super duplex stainless steel, it combines the desirable aspects of austenitic and ferritic steels. Higher chromium, molybdenum and nitrogen content results in a Pitting Resistance Equivalent Number (PREN) > 40, providing superior pitting and crevice corrosion capabilities over austenitic and duplex stainless steels in almost all corrosive media, and a critical pitting temperature Caution over 50°C. A version of the PREN formula also includes W as a positive effect on overall pitting resistance.
It offers higher strength than austenitic and 22% Cr duplex stainless steels and is listed to NACE MR 0175 for sour service and ASME for pressure vessel applications.
