Duplex Steel Buttweld Fittings consist mainly of chromium (about 22%), nickel, molybdenum, and nitrogen. The balanced chemistry lends them exceptional resistance to crevice corrosion, pitting, and stress corrosion cracking. Duplex steel mechanically offers high tensile and yield strength over normal stainless steels. Physically, the fittings have good hardness, high fatigue strength, and satisfactory dimensional stability under load. They also retain structural integrity under different thermal conditions and are strongly weldable, thereby being ideal for sophisticated piping systems.
