They provide reliable solutions for industries that need strong, wear-resistant engineering steel. With a strong commitment to excellence, the company produces round bars that adhere to strict international standards, making them perfect for use in automotive, machinery, construction, and heavy-duty equipment manufacturing. Thanks to their cutting-edge facilities and a skilled workforce, they ensure consistent dimensional accuracy, a superior finish, and reliable performance. Sadiki Metals is all about delivering durable, high-performance 20MnCr5 Round Bars that offer excellent machinability, toughness, and a long service life, even in the toughest operational environments.
20MnCr5 Round Bars are made from a low-carbon, alloy steel comprising manganese (0.70-1.00%) and chromium (0.80-1.10%), offering excellent hardenability, wear resistance and toughness. Mechanical properties include high tensile strength (up to 850 MPa), yield strength (up to 600 MPa), and good impact resistance, making it suitable for heavy-duty applications. The alloy’s ability to withstand fatigue and improve performance under high-stress conditions makes it ideal for automotive, engineering and manufacturing sectors, particularly in gear, shaft and bearing production.

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 incredibly popular in situations where you need a tough core and a high surface hardness. This makes them perfect for creating components that can withstand wear and tear while also being strong. Industries like automotive, mechanical engineering, and heavy machinery count on these bars to manufacture essential parts such as gears, shafts, crankshafts, connecting rods, spindles, and camshafts. They’re also great for components that face constant stress, sliding friction, or heavy loads. After undergoing carburizing or heat treatment, these materials gain outstanding wear resistance, making them ideal for transmission parts, machine tool components, and precision-engineered equipment that demands durability and reliable performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
