Phehlukwayo Metal is a reputable manufacturer and supplier of Stainless Steel 420 Hollow Bars, proudly based in Cape Town, South Africa. The company focuses on providing top-notch stainless steel products that boast impressive hardness, corrosion resistance, and precision engineering. Crafted through cutting-edge metallurgical and manufacturing techniques, these hollow bars deliver outstanding dimensional accuracy, consistent mechanical properties, and a sleek surface finish. Catering to sectors like automotive, tooling, engineering, and cutlery, Phehlukwayo Metal ensures dependable materials for applications that demand wear resistance, durability, and long-lasting performance in moderately corrosive settings.
Stainless Steel 420 Hollow Bars are martensitic stainless steels primarily made up of iron, featuring 12–14% chromium and 0.15–0.40% carbon, along with small amounts of manganese, silicon, and other alloying elements. This unique blend provides remarkable hardness, high tensile strength, and decent corrosion resistance. The hollow bar design helps reduce weight while preserving structural integrity, making it perfect for precision engineering. Additionally, 420 stainless steel can be heat-treated to achieve even greater hardness, ensuring that components exposed to friction, impact, or repeated mechanical stress remain durable and wear-resistant.

SS 420 hollow bars' excellent wear resistance enhances their performance by ensuring durability in high-friction environments. This property makes them ideal for cutting tools, medical instruments, and mechanical components, reducing maintenance needs and extending service life in demanding applications.
SS 420 hollow bars offer moderate high-temperature resistance but are generally not ideal for prolonged exposure to extreme heat. Their performance is best in applications requiring hardness and corrosion resistance under controlled or moderately elevated temperature conditions.
These Stainless Steel 420 Hollow Bars find their way into industries where strength, wear resistance, and corrosion protection are essential. They’re frequently used in the production of shafts, bearings, cutlery, surgical instruments, and hand tools that require edge retention and toughness. In automotive and engineering fields, hollow bars serve as components for axles, gears, and precision machinery parts, allowing for weight reduction without sacrificing strength. With their impressive hardness, durability, and moderate corrosion resistance, 420 stainless steel hollow bars are perfect for tooling, industrial, and decorative applications that demand both performance and reliability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
