[vc_row][vc_column][vc_column_text css=””]Carburizing is a thermo-chemical process used to increase the wear resistance of mechanical components such as gears.
\nBy enriching the surface layer of steel with carbon, the highest achievable hardness is obtained. The case depth may vary from a few tenths of a millimetre to several millimetres, depending on the exposure time at temperature.<\/p>\n

Due to the carbon enrichment of the base material, carburizing is typically performed on low-carbon steels (carbon content below 0.2%).
\nOne of the most commonly used steels is 18NiCrMo5.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=”47725″ add_caption=”yes” alignment=”left” onclick=”img_link_large” css=””][\/vc_column][\/vc_row][vc_row][vc_column]

Traditionally performed in oil, quenching may also be executed in pressurized gas (nitrogen) in modern installations designed to reduce distortion compared to conventional methods.<\/p>\n

Carburizing is carried out using gaseous carbon donors such as:<\/span><\/p>\n
