Hardening process
OUR PROCESSES
Using state-of-the-art technology and drawing on many years of experience, we offer a comprehensive range of processes designed to specifically enhance the properties of your components. Whether it’s hardening, nitriding, cryogenic treatment, annealing, or specialized processes—we ensure that your workpieces achieve the highest levels of hardness, wear resistance, and dimensional stability. You can rely on our customized solutions, which combine quality, reliability, and precision.
HARDENING
vacuum hardening
In vacuum hardening, your component is heated in a vacuum and then quenched using nitrogen under positive pressure. High-alloy materials are typically vacuum-hardened.
Protective gas hardening
In gas-protective hardening, the metal component is heated to the hardening temperature in a protective gas atmosphere and then rapidly cooled in an oil bath. Low-alloy materials are typically heat-treated in this manner.
induction hardening
In induction hardening, the areas to be hardened are heated using an induction current and then quenched with a water spray if necessary.
NITRIDING
gas nitriding
In gas nitriding, nitrogen is released from ammonia; at temperatures between 500°C and 600°C, this nitrogen penetrates the surface of the component, where it forms a wear-resistant nitride layer.
Plasma nitriding
In plasma nitriding, the surface layer of a workpiece is enriched with nitrogen in an ionized gas atmosphere. This results in clean component surfaces with significantly improved resistance to abrasion and wear.
Salt bath nitriding
In salt bath nitriding, the parts to be treated are immersed in a nitriding bath to increase their surface hardness and are then oxidized in a quenching bath.
FREEZING
Deep freezing
During deep-freezing, the steel is cooled to a temperature of -70°C to -150°C after hardening, which causes the retained austenite to be transformed into martensite.
GLOWING
Soft annealing
In soft annealing, a steel material is typically heated to just below the so-called A1 transformation point in order to achieve low strength and high ductility.
Stress-relief annealing
Stress-relief annealing reduces internal stresses in the microstructure of metal components, thereby minimizing the risk of undesirable dimensional and geometric changes during subsequent machining steps or when the component is put into service.
