ASTM A790 S32760 is a highly alloyed stainless steel with a composition that includes chromium, molybdenum, nitrogen, and a significant amount of both ferrite and austenite phases, which is also known as super duplex stainless steel(SDSS). S32760 offers exceptional resistance to corrosion. S32760 duplex steel exhibits higher strength compared to standard austenitic stainless steels, making it suitable for applications where high mechanical strength is required.
