“Your preferred partner for heat and surface treatment needs” contact


Surface Treatment Company (STC) is a world class supplier in thermal, thermo-chemical and surface treatments of mechanical components using several state-of-the-art production processes.

During the years, STC has installed a wide range of furnaces and auxiliary treatment machinery. The furnaces can be used for case hardening, gas nitriding and reheating combined with full automatic press hardening. The induction machines are available with HF and MF generators. Auxiliary treatments can consist of shot blasting or fully automatic straightening with crack detection of shafts. STC also provides metallurgical lab work with hardness testers, microscopes and part cleanliness measurement equipment.
