The company focuses on crafting precision-engineered flanges that adhere to global quality standards, making them perfect for tough industrial settings. With cutting-edge facilities and a commitment to innovation, Steve Flanges delivers dependable flange solutions for various sectors, including aerospace, marine, petrochemical, and power generation. Their Stainless Steel 17-4 PH Flanges are prized for their durability, outstanding mechanical properties, and long-lasting performance even in challenging conditions.
These flanges are made from a blend of iron, chromium (15–17%), nickel (3–5%), copper, and trace amounts of manganese, silicon, and niobium. They showcase exceptional mechanical strength, impressive hardness, and excellent resistance to both corrosion and oxidation. Even after heat treatment, they maintain good tensile strength (up to 1100 MPa) and toughness. The precipitation-hardening process boosts their durability and wear resistance, making them ideal for high-stress and high-temperature environments where strength and corrosion resistance are essential.
