Duplex Steel Pipe Fittings are composed of around 22–25% chromium, 5–7% nickel, 3–4% molybdenum, and nitrogen for added strength and corrosion resistance. This unique mix gives them twice the strength of standard stainless steel, along with excellent resistance to stress corrosion cracking, pitting, and crevice corrosion. They have a tensile strength of approximately 620 MPa and yield strength of about 450 MPa. Duplex steel maintains great weldability and toughness even at low temperatures, making it perfect for demanding industrial environments.
