Njabulo Stainless is a well-respected manufacturer and supplier of Stainless Steel 440C Pipes, proudly based in Cape Town, South Africa. The company has built a solid reputation for providing top-notch stainless steel products that are designed for high strength, hardness, and wear resistance. Their Stainless Steel 440C Pipes adhere to strict international standards and are widely utilized in industries that demand precision and durability. With state-of-the-art manufacturing facilities and a strong dedication to quality, Njabulo Stainless caters to sectors like aerospace, automotive, mechanical engineering, and petrochemicals, delivering reliable piping solutions for even the toughest operational environments.
These Stainless Steel 440C Pipes are primarily made up of iron, chromium (16–18%), carbon (0.95–1.20%), along with trace amounts of manganese, silicon, and molybdenum. This high-carbon martensitic stainless steel is known for its remarkable hardness and wear resistance, especially after undergoing heat treatment. The pipes boast a tensile strength of about 760–1000 MPa, a yield strength of around 450 MPa, and impressive toughness. 440C retains excellent mechanical properties even at elevated temperatures and shows good corrosion resistance in mildly corrosive and dry settings, making it a great choice for precision and heavy-duty applications.
