Induction hardening

What is induction hardening?

Induction hardening uses induced heat and rapid cooling (quenching) to increase the hardness and durability of steel. Induction is a no-contact process that quickly produces intense, localized and controllable heat. With induction, only the part to be hardened is heated.

Optimizing process parameters such as heating cycles, frequencies and coil and quench design results in the best possible outcomes.

What are the benefits?

Induction hardening boosts throughput. It is an extremely fast and repeatable process that integrates easily into production lines. With induction it is usual to treat individual workpieces. This ensures each separate workpiece is hardened to its own precise specifications. 

The optimized process parameters for each workpiece can be stored on your servers. Induction hardening is clean, safe and typically has a small footprint. And because only the part of the component to be hardened is heated, it is extremely energy-efficient.

 Where is it used?

Induction is used to harden numerous components. Here are just a few of them: gears, crankshafts, camshafts, drive shafts, output shafts, torsion bars, rocker arms, CV joints, tulips, valves, rock drills, slewing rings, inner and outer races.

 What equipment is available?

Hard Line is the SHAHAB Induction GROUP of hardening systems that offers vertical, horizontal, rotary table and centerless equipment. At the heart of our hardening solutions are  generators, available with output power ratings and frequencies ranging from 5–2000 kW and 0.3–350 kHz. SHAHAB Induction can also deliver turn-key hardening plants that include handling equipment, washing/straightening processes, process
devel- opment and service and support programs.

SHAHAB Induction hardening solutions are used by many of customers leading carmakers and their suppliers. High throughput, short lead times, assured quality and worker/environmental safety are key reasons why they choose our solutions.

 Induction hardening is faster than all other alternatives. At the same time it is highly controllable and repeatable making it perfect for integrating into automated production lines.
