Low Carbon Steel Case Hardening Process | Alpha Detroit

31 Aug 2017 In essence, the low carbon surface is infused with a supplementary carbon source. Just to underscore the issue, it's hard to case harden a low carbon steel when carbon is the required process instigator. Logically, we need A gas carburization process injects carbon monoxide into a heated furnace.

Carburising and carbonitriding are often referred to as case hardening. This is routinely with the charcoal treated parts, slow cool from the furnace to ball up the Case hardening mild steel. Most case hardened components are made from low alloy steel so they are hard enough when quenching in oil. To lower costs.
