Khaleed Stainless, a well-respected manufacturer and supplier based in Riyadh, Saudi Arabia, proudly offers top-notch **20MnCr5 Round Bars** that are widely utilized in the engineering and automotive sectors for components that demand exceptional strength and wear resistance. These alloy steel bars are crafted with meticulous attention to detail, adhering to stringent quality standards to ensure a superb surface finish and precise dimensions. Khaleed Stainless provides 20MnCr5 bars in a variety of sizes and conditions, making them perfect for heat treatment and carburizing processes, which are essential for applications that require toughness and fatigue resistance under significant mechanical stress.
The composition of 20MnCr5 Round Bars primarily includes 0.17–0.22% carbon, 1.00–1.30% manganese, and 0.15–0.30% chromium. This unique blend of alloys offers remarkable hardenability, making these bars ideal for carburizing and case hardening, which enhances surface wear resistance while keeping the core tough. Before heat treatment, the mechanical properties typically showcase a tensile strength of around 600 MPa. After undergoing carburizing and quenching, these bars achieve impressive surface hardness and fatigue strength, making them perfect for heavy-duty applications that require both wear resistance and impact toughness.
