Super duplex steel pipe fittings consist of sophisticated alloys comprising about 25% chromium, 7% nickel, 3–4% molybdenum, and nitrogen with a ferritic-austenitic microstructure. Their chemical composition provides them with high resistance against pitting, crevice corrosion, and chloride stress corrosion cracking. They possess tensile strength of about 800 MPa and yield strength of about 550 MPa, significantly more than common austenitic stainless steels. These fittings also offer superior weldability, fatigue resistance, and long lifespan in extremely corrosive and high-pressure conditions. Their chemical and mechanical properties render them suitable for demanding industrial conditions.
