Induction Hardening
Induction Hardening is a surface heat treatment process in which components are rapidly heated using electromagnetic induction and then immediately quenched to achieve a hardened surface layer. This process provides high surface hardness while maintaining a tough and ductile core.
Induction hardening is highly suitable for components requiring localized hardening, minimal distortion, and precise control over case depth. It is widely used for improving the performance and service life of critical engineering components.
Key Benefits
- High surface hardness with tough core
- Localized and selective hardening
- Minimal distortion and oxidation
- Improved wear and fatigue resistance
- Short processing cycle time
Typical Applications
- Shafts and axles
- Gears and sprockets
- Pins and rollers
- Camshafts and crankshafts
- Machine and automotive components
Induction hardening is suitable for medium to high carbon steels (typically 0.3%–0.6% carbon), alloy steels, and certain cast irons. It is commonly used for shafts, gears, pins, rollers, and automotive components.
Induction hardening can achieve surface hardness of approximately 50–65 HRC, depending on the material composition and prior heat treatment condition.
The process is very fast, with heating and quenching typically completed within a few seconds to a few minutes per component, depending on size and case depth requirement.
The processing cost depends on material type, component size, and batch quantity. As each job has different requirements, pricing is determined accordingly. Please contact us for detailed quotation and technical discussion.
