Carburizing is a thermochemical treatment that aims to increase superficial hardness by diffusing carbon into the treated part and quenching it. However, depending on the application, the carburizing effective case depth must be adapted. High scale parts with high loads, such as in mining or wind turbine industry, require high case depths. Deep case carburizing consists in case depths from 2.5mm to above 4mm.
The present work shows results of deep case low pressure carburizing performed in our vacuum oil quenching furnaces with the acetylene multi-boosts ALLCARB® process, including our vertical vacuum oil quenching furnace V6THC. Several carburizing temperatures and steel grades are studied.
