Njabulo Stainless stands out as a top-notch manufacturer and supplier of Stainless Steel 310H Bolts in Cape Town, South Africa. They provide high-quality fasteners designed for exceptional strength, durability, and resistance to high-temperature corrosion. Crafted from a special blend of high-chromium, high-nickel austenitic stainless steel with added carbon, these bolts maintain their mechanical integrity even in extreme heat. Perfect for furnace components, kilns, petrochemical plants, and power generation systems, Njabulo Stainless guarantees precision manufacturing and rigorous quality control, ensuring their bolts meet international standards and deliver reliable performance in tough industrial settings.
Stainless Steel 310H Bolts 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. They boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of 35%, which translates to excellent toughness and mechanical stability. With a density of 8.0 g/cm³ and a melting range of 1390–1420°C, these bolts maintain their corrosion and oxidation resistance, as well as their structural integrity, even under extreme heat and challenging industrial conditions.
