Aiman Metals stands out as a reliable manufacturer and supplier based in Kuala Lumpur, Malaysia, specializing in top-notch 20MnCr5 Round Bars designed for tough engineering and industrial tasks. These bars are celebrated for their remarkable wear resistance, toughness, and hardenability, making them a go-to choice for components that need a resilient core and a hard surface after case hardening. At Aiman Metals, we ensure that our bars are crafted to exact specifications and meet rigorous quality standards, guaranteeing consistent mechanical performance. Offered in a variety of sizes, finishes, and lengths, our 20MnCr5 Round Bars are highly sought after in the automotive, machinery, and heavy equipment sectors.
The 20MnCr5 Round Bars are low-carbon alloy steels, featuring around 0.17–0.22% carbon, 1.10–1.40% manganese, and 0.90–1.20% chromium, along with trace amounts of silicon, phosphorus, and sulfur. This unique blend gives them impressive core strength, excellent wear resistance, and the capability to achieve outstanding surface hardness through processes like carburizing or heat treatment. Typically, their mechanical properties include a tensile strength ranging from 550–750 MPa, yield strength around 300–400 MPa, and high impact toughness, making them perfect for heavy-duty applications.
