Carburizing is a thermochemical heat treatment process for hardening steel components in which the surface hardness is increased by the addition of carbon. The aim here is to increase wear resistance in order to achieve a longer component service life. Low-pressure carburizing in the vacuum furnace with the CARB PLUS system is carried out using acetylene. This case hardening process is carried out at low pressures and temperatures in the range of up to 1070°C. Benefit from the man advantages of low-pressure carburizing compared to conventional carburizing processes!
