The biggest feature of Isonite treatment method is that thanks to low temperature treatment suitable for each type of material, there is little change in product size after treatment, short processing time (0.5 ~ 3 hours). . Treatment by dipping the product into a salt bath with a temperature of 580℃ helps to form a hardening permeable layer on the surface of the product, below is a diffusion layer. Isonite treatment helps prolong the service life of iron and steel materials.
