SHOT BLASTING
SHOT BLASTING :–The purpose of blasting after heat treatment is to remove any oxidation or scale that has formed in the forging or heat treating process. During heat treating of forgings, oxidation can form during annealing, normalizing, hardening, or tempering operations depending on the particular process parameters. Blasting will easily remove this surface oxidation, making any downstream operations like lot number stamping and machining much easier.
