Super Duplex Steel S32760 pipe fittings are made from a high-performance alloy composed primarily of 24-25% chromium, 6-8% nickel, 3-4% molybdenum, and small amounts of nitrogen, manganese, and other elements. This combination provides excellent resistance to corrosion, especially in chloride environments. The mechanical properties include high tensile strength (up to 1000 MPa), yield strength (around 650 MPa), and elongation of 25%. Super Duplex S32760 also exhibits superior toughness, stress corrosion cracking resistance, and high resistance to pitting and crevice corrosion, making it ideal for harsh environments.

The Super Duplex Steel Pipe Fittings from Zain Fittings are crafted from a unique blend of materials, including chromium (24–26%), nickel (6–8%), molybdenum (3–5%), nitrogen, and a well-balanced amount of iron. This special composition significantly boosts their resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, these fittings deliver high tensile strength (usually exceeding 750 MPa), excellent yield strength, and outstanding impact toughness, even in freezing temperatures. Their dual-phase microstructure, which combines ferritic and austenitic phases, ensures superior structural integrity, making them perfect for the challenging environments found in Cape Town’s industrial sectors.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
