Cast steel angular grit is produced by crushing specially heat treated shot pellets. Its behavior characteristics in service are very much dependent upon the hardness selection of GP, GB, GL or GR grit.

Although harder and more aggressive than GB Steel Grit, GL also loses its sharp edges during abrasive blasting and is particularly suited to descaling and surface preparation applications.

Microstructure

 N/A 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.
