Super Duplex 32760
Introduction :
Alloy 32760 is a Super Duplex 32760 Stainless Steel 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 developed chromium, molybdenum and nitrogen contents consequence in a Pitting Resistance Equivalent number (PREN) of >40, if pitting and crevice corrosion resistance larger 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.
