Njabulo Stainless, based in Cape Town, South Africa, is a trusted manufacturer and supplier of Stainless Steel 440C Coils. These coils are precision-rolled strips of 440C stainless steel wound into coil form for easy handling, storage, and fabrication. Grade 440C is a high-carbon martensitic stainless steel known for its exceptional hardness, wear resistance, and mechanical strength. Njabulo Stainless ensures smooth surfaces, uniform thickness, and precise dimensions. These coils are widely used in industrial applications where durability, corrosion resistance, and high performance are critical, making them ideal for manufacturing, engineering, and machinery components.
Stainless Steel 440C Coils are made from martensitic stainless steel 440C, containing high carbon (0.95–1.20%) and chromium (16–18%). This composition provides excellent hardness, tensile strength, and wear resistance, while maintaining moderate corrosion resistance. The coils have high fatigue strength, toughness, and dimensional stability, making them suitable for heavy-duty industrial applications. Precision rolling ensures uniform thickness and smooth surfaces, allowing easy fabrication and forming. These properties make 440C coils ideal for components that require long-lasting performance, high strength, and resistance to wear in demanding industrial environments.
