Work Smarter with Edcon Steel

Cut Cleanly: For DIY machining, use sharp tooling and appropriate cutting speeds, especially on alloy grades like 8620. Case hardening steel round bars can be cut to size in-store or with your online order.

Choose the Right Grade: 1020 suits general fabrication and light case hardening, 8620 is ideal for high-wear, high-load components, and 1214 offers excellent machinability where welding is not required.

Store to Prevent Rust: Case hardening steels are supplied in a plain finish. Store bars undercover and apply a light oil if they will be kept for extended periods before use.

Handle Safely: Round bars can be heavy, particularly in larger diameters. Use correct lifting methods and de-burr cut ends to reduce handling risks.

Common Uses and Sectors: Case Hardening Steel

Case hardening steel round bars are used wherever a hard surface and tough core are required. A classic example is gear wheels, where the gear teeth need to be extremely hard to resist wear, but the gear’s core must absorb shocks without cracking. These properties also make case hardening steels ideal for drive shafts, camshafts, bushings, clutch parts, and heavy-duty pins or rollers.

Industries such as automotive, machinery manufacturing, mining, and agricultural equipment rely on 8620 and similar alloy case-hardening steels for critical components (like gearbox gears and axle shafts) that must endure constant friction and high loads.

In the construction and engineering sectors, case hardening steel is used for things like crane pins, hardened fasteners, and wear plates in equipment; anywhere a part needs to last longer under stress.

At the same time, these round bars (especially 1020 mild steel) can serve in general fabrication when unhardened, offering a good all-purpose engineering steel for making jigs, fixtures, brackets or any part that might later be carburised for extra hardness.
