Duplex Steel S31803 / S32205 manifold valves are crafted from austenitic-ferritic stainless steel alloys, delivering a fantastic blend of strength and corrosion resistance. Their unique composition features chromium, nickel, molybdenum, and nitrogen, which together offer impressive resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. These valves boast remarkable mechanical properties, including high tensile and yield strength—nearly double that of standard austenitic stainless steels—along with excellent fatigue and impact resistance. With reliable performance in both low and high temperatures, Duplex manifold valves are perfect for tough process conditions in demanding industrial settings.
