We are as a renowned service provider, engaged in providing reliable and cost effective Induction Hardening services across Kolkata, India. In order to render the job, we have hired proficient and diligent workmen who have extensive knowledge of this domain. Customers are provided the Induction Hardening services at reasonable charges.
- The process involves progressive heating of the components within suitably designed inductor coils generating alternating current of desired frequency - Quick Soaking - and immediate quenching by pressure jets of water/polymer solution.
- "Quick heat-Quick cool" method ensures very fine surface microstructure.
- Alternating current through inductor coils generates electromagnetic field including eddy current on the surface area of the job.The skin current produces skin heating only which excludes the possibility of mass effect in eventual quenching. So induction-hardened jobs always archive more surface hardness then volume-hardened jobs, particularly for big masses. In volume-hardened jobs the surface hardness becomes reduced by self-tempering due to evolution of enormous core-heat during martensitie transformation in quenching.
- Quick processing means minimum time of soaking at the elevated temperature. So no scale is formed on the work surface.
- Improved endurance limit is fatigue.
