Phehlukwayo Metal is a reliable manufacturer and supplier of Stainless Steel 420 Flat Bars, proudly based in Cape Town, South Africa. The company focuses on delivering top-notch stainless steel products that are celebrated for their hardness, resistance to corrosion, and outstanding machinability. Crafted through advanced metallurgical processes and precise rolling techniques, these flat bars boast exceptional dimensional accuracy, consistent mechanical properties, and a sleek surface finish. Catering to industries like cutlery, tooling, automotive, and manufacturing, Phehlukwayo Metal guarantees dependable materials for applications that require durability, strength, and long-lasting performance in both regular and mildly corrosive environments.
Stainless Steel 420 Flat Bars are martensitic stainless steels primarily made of iron, containing 12–14% chromium and a carbon content ranging from 0.15–0.40%, along with small amounts of manganese, silicon, and other elements. This unique composition results in impressive hardness, high tensile strength, and moderate resistance to corrosion. The 420 stainless steel can be heat-treated to achieve even greater hardness, making it ideal for wear-resistant applications. It also offers good machinability, polishability, and edge retention, striking a balance between toughness and precision performance for tooling and engineering components.

Stainless Steel 420 Flat Bar is commonly used in applications requiring high strength, wear resistance, and moderate corrosion resistance. It is often found in the manufacturing of surgical instruments, valves, knives, bearings, shafts, and other precision machinery components.
Stainless Steel 420 typically has a hardness range of 50-55 HRC (Rockwell Hardness). When heat-treated, it can achieve higher hardness levels, making it suitable for applications requiring wear resistance, such as cutlery, tools, and industrial components.
Yes, Stainless Steel 420 Flat Bar can be heat treated to improve strength. Through processes like annealing, hardening, and tempering, its hardness, wear resistance, and overall strength can be enhanced, making it ideal for demanding applications like cutting tools.
These Stainless Steel 420 Flat Bars find extensive use in industries where hardness, wear resistance, and corrosion protection are crucial. They’re often used in the production of knives, cutlery, surgical instruments, and hand tools because of their ability to maintain a sharp edge. In the automotive and engineering fields, they serve as shafts, fasteners, blades, and machine components. Additionally, the material is perfect for decorative applications and industrial tooling that require polished surfaces and high durability. Its versatility, strength, and resistance to corrosion make it a go-to choice for a wide range of industrial and commercial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
