Njabulo Stainless stands out as a top-notch manufacturer and supplier of Stainless Steel 310H Flanges right in Cape Town, South Africa. They offer flanges that are not just premium-quality but also built to withstand high temperatures, ensuring durability and resistance to corrosion. Crafted from a special blend of high-chromium, high-nickel austenitic stainless steel with a bit more carbon, these flanges excel in resisting oxidation and scaling, even in extreme heat. Perfect for industries like chemical processing, petrochemicals, power generation, and high-temperature piping systems, Njabulo Stainless guarantees precision in manufacturing and rigorous quality control, delivering flanges that meet international standards for long-lasting reliability and performance in tough industrial settings.
Stainless Steel 310H Flanges are made up of chromium (24–26%), nickel (19–22%), iron, and a higher carbon content (0.08–0.25%) to boost their high-temperature strength. This alloy boasts a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of 35%, ensuring they are mechanically stable and durable. With a density of 8.0 g/cm³ and a melting range of 1390–1420°C, SS 310H Flanges maintain their structural integrity, resist scaling, and perform reliably in high-temperature and corrosive industrial environments.
