Stainless steel 410 forged fittings are mainly made from a martensitic alloy containing iron, chromium (11-13%), a small amount of carbon (0.15%), manganese, silicon, nickel etc. This composition makes it extremely tough and corrosive against destruction. Mechanical properties of SS 410 include a tensile strength of 758 MPa (110,000 psi), a yield strength of 205 MPa (30,000 psi), and elongation of 25%. These materials provide high corrosion resistance and are commonly used in applications requiring strength and moderate corrosion resistance.

The Super Duplex Steel Pipe Fittings we offer are made up of a unique blend of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), nitrogen, and just the right amount of iron. This special composition boosts their resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, these fittings deliver high tensile strength (usually over 750 MPa), excellent yield strength, and impressive impact toughness, even in freezing temperatures. Their dual-phase microstructure, combining ferritic and austenitic phases, ensures superior structural integrity, making them perfect for the demanding industrial environments in Cape Town.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
