Anti Carburizing
We can provide anti-carburizer which is imported from Japan.
We are distributor of Carbon Killer which manufactured by “Bansei Chemical Heavy Industry”
Why need Anti Carburizing
- If there is finishing machining in the post-process, carburized item is too hard to scrape.
- At the welding process, large amount of carbon makes crack.
- The carburized part is vulnerable to impact. It prevents the screw thread from being damaged
Mechanism of Carburizing
- Carbon is added on the surface, then quenching Metal surface become harden.
(inside remain toughness)
Mechanism of carburizing inhibitor
- Cover the metal surface and prevent curburizing
