Typically, Duplex Steel Buttweld Fittings consist of 22–23% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, and nitrogen. This unique composition results in impressive tensile strength (~620 MPa) and yield strength (~450 MPa), nearly double that of standard stainless steel. Our fittings come in various forms, including elbows, tees, reducers, caps, and stub ends, available in both seamless and welded options. They maintain excellent toughness even in low temperatures and provide superior resistance to chloride-induced corrosion and erosion.
