The JB/T 4215-1996 boronizing standard defines the material, process, equipment and mass inspection requirements for boronizing treatment. It is suitable for all kinds of structural steel, tool steel, stainless steel and cast iron workpieces that need to improve abrasion resistance, corrosion resistance and oxidation resistance. The standard includes the ratio of boronizing agent, parameter setting of boronizing process, equipment configuration and post-treatment steps. It also specifies the mass inspection standard of boronizing layer, including microstructure, Hardness and depth determination to ensure the mass and effect of boronizing treatment. At the same time, the standard emphasizes the safety technical requirements in the boronizing process to ensure production safety.
