Hardening is a heat treatment process in which steel is kept at a suitable temperature until it transforms into austenite and then quickly quenched. Based on the carbon content of the steel, the austenitizing temperature is decided. Extending the heating time completely transforms the core into austenite. The final microstructure of the hardened steel is either ferrite or martensite. Kepka has designed a durable, practical device. The furnace is made of materials that protect the bottom from damage, ergonomic to reduce operating costs. We design furnaces with perfect temperature distribution and an emphasis on the shortest possible route to the bath for the hot charge. In this way, we avoid the need to cooperate with specialized companies and save time, effort and money.
