The stainless steel 410 Buttweld fittings are made of a martensitic stainless steel alloy containing about 11.5-13.5% chromium. These properties provide excellent corrosion resistance, especially in lightly corroded areas. Mechanical characteristics include tensile strength of 550-750 MPa, yield strength of 205-510 MPa, and hardness of 35 to 45. HRC Stainless steel 410 exhibits moderate ductility and is heat-treatable, making it suitable for high temperature application. It is commonly used in chemical processing, heat exchangers, and food processing applications where strength and corrosion resistance are required.

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 found 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.
