Njabulo Stainless is a reputable manufacturer and supplier located in Cape Town, South Africa, known for its top-notch Stainless Steel 304H bolts. With a solid track record of providing dependable and durable fastening solutions, Njabulo Stainless serves a variety of industries, including petrochemical, construction, and marine sectors. The company prides itself on excellence, ensuring that all its products adhere to international quality standards and performance expectations. The Stainless Steel 304H bolts from Njabulo Stainless are specifically designed for high-temperature applications, offering enhanced strength, corrosion resistance, and long-lasting performance even in tough environments.
These bolts are made from an austenitic stainless steel alloy that has a higher carbon content (0.04–0.10%) to boost high-temperature strength. Their chemical makeup features chromium (18–20%), nickel (8–11%), along with controlled amounts of manganese, silicon, phosphorus, and sulfur. With impressive mechanical properties, these bolts boast a minimum tensile strength of 515 MPa and a yield strength of 205 MPa, along with good elongation and toughness. The 304H bolts are particularly resistant to oxidation and scaling at high temperatures, making them perfect for heat-intensive applications while ensuring they maintain their structural integrity and resist corrosion.
