Duplex Steel Buttweld Fittings are made from a carefully balanced blend of austenitic and ferritic stainless steel, usually containing 22–25% chromium, 4–6% nickel, 3–5% molybdenum, and small amounts of nitrogen. This distinctive composition offers exceptional resistance to pitting, stress corrosion cracking, and general corrosion when compared to standard stainless steels. In terms of mechanics, they boast high tensile strength, excellent toughness, and impressive durability at both room and elevated temperatures. Duplex stainless steel effectively combines the strength of ferritic steel with the corrosion resistance of austenitic steel, ensuring long-lasting performance in harsh environments while maintaining dimensional stability and resistance to deformation under pressure.
