Alloy Steel Round Bars
Source 20MnCr5 case-hardening steel round bars for gears, shafts and automotive parts in verified sizes, conditions and quantities.

Jain Steels Group supplies 20MnCr5 alloy steel round bars for gears, pinions, shafts and automotive or engineering components. The grade is commonly selected where a hard, wear-resistant case and a tougher core are required after a controlled downstream case-hardening process. Final material selection and heat treatment must be approved by the buyer's engineer.
Component performance depends on the ordered material condition, machining route and the downstream carburising and heat-treatment cycle. Jain Steels Group does not substitute a grade or heat-treatment recommendation for the buyer's drawing and applicable standard. Share the case-depth, hardness and test requirements as part of the technical enquiry.
