Microstructure

Well controlled manufacturing gives die a martensitic structure that blends the iron and carbon atoms in the finest and most ideal way possible. This structure produces a homogeneity or hardness and resistance throughout the shot. Without this structure the shot would not have the resistance necessary for the applications in which it is used.
