Phehlukwayo Metal, located in Cape Town, South Africa, is a leading manufacturer and supplier of premium-quality 20MnCr5 Round Bars, designed to meet the demanding needs of engineering, automotive, and industrial applications. Known for its precision manufacturing, strict quality control, and customer-focused approach, the company delivers products that ensure strength, reliability, and performance. With modern production facilities and adherence to international standards, Phehlukwayo Metal has built a reputation for supplying durable and consistent materials that support long-lasting mechanical performance in both local and global markets.
20MnCr5 Round Bars have a typical chemical composition of Carbon (C) 0.17–0.22%, Manganese (Mn) 1.10–1.40%, Chromium (Cr) 1.00–1.30%, Silicon (Si) 0.40% max, Sulfur (S) 0.035% max, Phosphorus (P) 0.035% max, and the balance Iron (Fe). These elements give the alloy excellent hardenability, wear resistance, and toughness. Mechanically, it exhibits a tensile strength of around 600–850 MPa, yield strength of about 340 MPa, and elongation of 12–15%, making it ideal for applications requiring both surface hardness and core strength.

Yes, 20MnCr5 Round Bars can be used for underground applications due to their high strength and durability.
Yes, 20MnCr5 Round Bars may require corrosion protection coatings for enhanced durability in harsh environments.
Choose 20MnCr5 Round Bars based on required strength, wear resistance, and application-specific environmental conditions.
20MnCr5 Round Bars are widely used in automotive and engineering industries for manufacturing components that demand high wear resistance and fatigue strength. Common applications include gears, shafts, camshafts, crankshafts, fasteners, and connecting rods. The material’s ability to undergo carburizing and hardening treatments allows it to achieve a tough core with a hard surface, enhancing its performance under heavy loads. It is also suitable for use in machinery parts, transmission systems, and tools exposed to continuous stress. These properties make 20MnCr5 Round Bars a reliable choice for precision-engineered mechanical components.
