Product Description
20MnCr5 Steel Bars are an engineering metal with low alloy content. These case hardened bars are designed for use in parts requiring core tensile strength ranging from 1000 to 1300 N/mm2. It is found in piston bolts, camshafts, spindles, boxes, gears, shafts, and other mechanically controlling components. 20MnCr5 Steel Bars are also used in applications where wear resistance is a primary requirement. We can customize the weight of 20MnCr5 Steel Bars as per the buyer's or application's needs. It is commonly used following carburizing quenching or quenching and tempering. You can trust us and buy 20MnCr5 Steel Bars with full quality guarantee.
Precision Engineering and Quality AssuranceEach 20MnCr5 steel bar undergoes advanced hot rolling or forging, followed by precise surface treatments such as peeling, grinding, and polishing. With strict adherence to quality benchmarks like DIN, EN, BS, and IS standards, the bars offer consistent mechanical properties and dimensional accuracy. Custom tolerances (h7, h8, h9) and defect-free finishes ensure optimal performance in demanding applications.
Versatile Applications across IndustriesOwing to their high impact strength and good machinability post-annealing, 20MnCr5 steel bars are extensively used in automotive components, gears, shafts, and engineering parts. Their durability and adaptability to various surface treatments make them suitable for both moderate and severe operating environments when additional corrosion resistance is required.

Export standard packaging ensures secure transport, and minimum order quantities are determined as per manufacturer policy. As an exporter, manufacturer, and supplier from India, we deliver reliably to global markets.
FAQs of 20MnCr5 Steel Bars:
Q: How are 20MnCr5 steel bars processed to ensure desired mechanical properties?
A: These bars are manufactured through hot rolling or forging, followed by annealing, hardening, or tempering depending on the required supply condition. Surface treatments such as peeling, grinding, and polishing further enhance their mechanical characteristics and surface finish.
Q: What applications are most suitable for using 20MnCr5 steel bars?
A: 20MnCr5 steel bars are ideal for automotive parts, gear manufacturing, heavy-duty shafts, and various engineering components due to their high impact strength and good machinability after annealing. Their properties make them especially suited for parts subjected to dynamic loads.
Q: When is additional surface treatment recommended for these steel bars?
A: While 20MnCr5 steel offers moderate corrosion resistance, additional surface treatments are recommended for severe operating conditions. Processes such as chroming, nitriding, or phosphating can be applied based on the applications environmental demand.
Q: Where can custom dimensions or special tolerance requirements be accommodated?
A: Custom diameters, lengths, and tolerances (h7, h8, h9, or as specified) can be supplied on request. Customers should specify their exact requirements during inquiry or order placement to ensure seamless production and delivery.
Q: What benefits does the annealed condition provide in terms of machinability?
A: The annealed condition reduces internal stresses and softens the material, resulting in improved machinability. This makes the bars easier to cut, shape, or finish, reducing tool wear and enhancing production efficiency.
Q: How are 20MnCr5 steel bars typically packed for export or domestic supply?
A: Bars are bundled with steel strips and can be packed according to export standards for international shipments. Customized packaging solutions can be arranged to protect the material during transit and handling.
