Heat treatment
Heat treatment of steel, cast and sintered materials including case hardening, carbonitriding, hardening/tempering, gas nitriding, gas nitrocarburizing, as well as vacuum hardening and deep-freezing.
Case hardening
Case hardening of components for surface hardening, including partial treatments depending on feasibility; for unalloyed, low-alloy and deep-drawing steels.
Vacuum hardening / deep-freezing
Vacuum hardening with subsequent deep-freezing and tempering to achieve the required operating hardness; without surface corrosion and with a low retained-austenite content.
Gas nitriding
Gas nitriding of steel, cast and sintered materials to increase surface hardness, with low distortion, good polishing capability and minimal change in dimensions.
Gas nitrocarburizing
Gas nitrocarburizing for surface hardening with improved corrosion and wear resistance, increased fatigue strength and low change in dimensions.
Heat treatment under nitrogen / normalizing
Annealing of semi-finished products and workpieces to achieve defined material properties; reduces workpiece stresses and can improve machinability.
Annealing under hydrogen
Annealing in a hydrogen atmosphere to reduce carbon at the component surface and to improve magnetic coercive field strength.
Blasting technology
Glass bead, corundum and ceramic blasting for surface preparation, cleaning, rust removal, surface finishing and surface strengthening blasting.
Crack testing
Crack testing of components as a testing and inspection service in the context of heat treatment.
Component cleaning
Component cleaning as an additional service alongside heat treatment and surface processes.
