Njabulo Stainless, located in Cape Town, South Africa, is a well-respected manufacturer and supplier of top-notch Stainless Steel 304H flanges. Renowned for their precision engineering and durability, Njabulo Stainless caters to a variety of industries, including petrochemical, power generation, marine, and construction. Their 304H flanges are crafted to perform reliably even in extreme conditions, particularly at high temperatures. Built to comply with strict international standards, these flanges offer outstanding corrosion resistance, strength, and a long service life, making them perfect for critical applications where safety and performance are crucial.
Stainless Steel 304H flanges are made from an austenitic stainless steel alloy that has a higher carbon content (0.04–0.10%) to boost strength at elevated temperatures. The chemical composition includes chromium (18–20%), nickel (8–11%), and controlled amounts of manganese, silicon, phosphorus, and sulfur. These flanges boast a tensile strength of at least 515 MPa and a yield strength of 205 MPa, along with impressive elongation and toughness. The alloy’s excellent resistance to oxidation and scaling at high heat ensures durability and structural integrity in challenging environments.
