Super Duplex Steel S32750 pipe fittings are composed primarily of iron, with chromium (25-26%), molybdenum (3-4%), nickel (6-8%), and a small amount of nitrogen (0.24-0.32%). This composition provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride environments. The mechanical properties of S32750 include a high tensile strength of 80-100 ksi (550-690 MPa), yield strength of 50-75 ksi (345-515 MPa), and elongation of 25%. This alloy offers superior toughness, high strength, and excellent resistance to both corrosion and fatigue.

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.
