Technical Corner - S32760 Super-Duplex Stainless Steel

A short article providing an overview of S32760, a 25% Cr Super Duplex Stainless Steel.

Alloy 32760 is a #superduplex #stainlesssteel supplied in the hot worked and solution annealed condition. As a super duplex stainless steel, it combines the desirable aspects of both austenitic and ferritic grades. The higher chromium, molybdenum and nitrogen contents result in a Pitting Resistance Equivalent number (PREN) of 40, providing pitting and crevice corrosion resistance superior to austenitic and duplex stainless steels in almost all corrosive media, and a Critical Pitting Temperature exceeding 50°C nb. versions of the PREN formula also include W as a positive influence on overall pitting resistance.

It provides higher strength than both austenitic and 22% Cr duplex stainless steels, and is listed in NACE MR 0175 for sour service and ASME for pressure vessel applications.

Langley Alloys stocks S32760 as solid bar, plate and seamless pipe across our sites in the UK and USA.
