Our **Duplex Steel Forged Fittings** consist of about 22% chromium, 5–6% nickel, 3% molybdenum, along with trace amounts of nitrogen and other alloying elements. This special mix results in high tensile strength (around 620 MPa) and yield strength (approximately 450 MPa), along with excellent resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. The range of forged fittings we offer includes elbows, tees, reducers, caps, and couplings, all boasting better mechanical properties than their cast or welded counterparts.
