Super Duplex Check Valves are generally made from super duplex stainless steel alloys like UNS S32750 or S32760. Their composition features high levels of chromium (24–26%), nickel (6–8%), molybdenum (3–4%), and nitrogen, which together create a well-balanced austenitic-ferritic microstructure. This unique blend results in remarkable mechanical properties, such as high tensile and yield strength, excellent toughness, and outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. These valves are built to maintain strength and reliability even under high pressure and temperature conditions.
