Dhruv Metals, a well-respected manufacturer and supplier located in Hyderabad, India, is all about delivering top-notch 20MnCr5 Round Bars that cater to the demanding needs of various industrial applications. These bars are crafted using cutting-edge techniques and meet international quality standards, ensuring they provide exceptional strength, wear resistance, and machinability. Dhruv Metals prides itself on maintaining precise dimensional accuracy, consistent quality, and timely delivery, making them a reliable partner in the engineering and manufacturing industries. With a strong commitment to excellence, Dhruv Metals offers 20MnCr5 Round Bars that perform dependably in high-stress environments, making them perfect for automotive, gear, shaft, and transmission component manufacturing.
When it comes to composition, 20MnCr5 Round Bars are low-alloy steels that typically contain 0.17–0.22% Carbon, 1.10–1.40% Manganese, and 0.90–1.20% Chromium, along with trace amounts of Sulphur, Phosphorus, and Silicon. These bars are known for their impressive hardenability and strength after carburizing. On the mechanical side, they boast a tensile strength of 900–1100 MPa, a yield strength of around 450 MPa, and an elongation of about 10–12%. With a Brinell Hardness of roughly 260 HB (in the annealed state) and good impact resistance, 20MnCr5 is a go-to choice for components that need high fatigue strength and surface hardness.

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.
Industries that require components with outstanding wear resistance, toughness, and high surface hardness after heat treatment extensively use 20MnCr5 Round Bars. They’re commonly found in the automotive and mechanical engineering sectors, where they’re used to manufacture gears, shafts, crankshafts, steering components, and camshafts. Thanks to their high hardenability, these bars are perfect for applications that involve surface carburizing and quenching, ensuring they last a long time. They’re also great for drive elements, gear wheels, transmission shafts, and piston pins. With their robust mechanical properties, they are a favored option in both heavy-duty and precision-machined engineering applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
