Fusion of gas carburizing and vacuum technology! No oxygen components in the atmosphere, no grain boundary oxidation, and excellent surface finish!
"Direct Carburizing (Multi Carbo)" is a new concept carburizing method that combines gas carburizing and vacuum technology. This technology utilizes vacuum (reduced pressure) to drastically reduce carrier gas and only uses a very small amount of chain-like unsaturated hydrocarbon gas as the carburizing gas. Since the atmosphere does not contain oxygen components, the alloy components on the surface do not oxidize, resulting in a good finish. It is environmentally friendly, high quality, and reduces operating costs by half. 【Features】 ■ No grain boundary oxidation (oxidation of surface alloy components) ■ Carburizing of pores is possible ■ High concentration carburizing is possible ■ Extremely shallow carburizing (30-50μm) is possible ■ Vacuum hardening is possible *For more details, please refer to the PDF document or feel free to contact us.
