Induction Hardening Guide: Surface Hardening with Low Distortion

Induction Hardening Guide: Surface Hardening with Low Distortion

Short answer: Induction hardening uses a high-frequency magnetic field to rapidly heat just the surface of a steel part, then quenches it in place for a hard, wear-resistant case with almost no distortion to the soft, tough core.

How It Works

A copper coil induces eddy currents that heat the skin in seconds; the part is spray-quenched before the core warms. It is a partner to Nitriding Vs Carburizing y Metal Austempering Guide and follows the strength logic in Yield Strength Vs Tensile Strength y Metal Fatigue Endurance Limit; relate to Metal Surface Treatment Guide.

Where It Pays Off

Shafts, gears, cam lobes and rail heads gain a hard case with a ductile core; tie wear resistance to Metal Wear Mechanisms Guide, check depth by Metal Hardness Testing Methods, and finish per Steel Hardness Vs Strength Guide y Metal Burr Deburring Guide.

QA & Supply

Confirm case depth and cracks by Metal Ndt Guide, document per Mill Test Certificate Guide, and protect via How To Prevent Metal Rust. HXSCO supplies hardening-grade bars matched to the process.

Preguntas frecuentes

What is induction hardening?

A high-frequency field heats only the surface, which is then quenched for a hard, wear-resistant case.

What metals can be induction hardened?

Carbon and low-alloy steels, and some cast irons, that respond to quench hardening.

Why is distortion low?

Only the thin surface is heated and quenched, so the core stays cool and stable.

How deep is the hardened case?

Typically 0.5 to 5 mm, controlled by frequency, power and scan speed.

Do you supply hardening-grade steel?

HXSCO supplies bars and blanks in grades selected for induction hardening.
