SAE GL-18 Steel Shot for Shotblast Material and Surface Preparation
High carbon steel shot
High carbon steel shot is used in the majority of the wheel blast applications and creates a dimpled, peened
surface. Only the shot's skin suffers from the impact and very thin flakes will progressively part from the
shot, which itself stays round throughout its life cycle. Our steel shot is very durable with high resistance
to impact fatigue, giving it an effective and quick cleaning rate.
Application
·Sand removal of large sized castings, scale removal of large sized products from forging,stamping, dieforging, drawing and rolling or after heat treatment (e.g. pipes, sections, plates,fittings, wire).
·Sand removal of large and medium sized castings, scale removal of forging and heat-treated work pieces,surface blast cleaning of steel plates, sections and steel structures, shot peening of work pieces, cutting of granite.
·Sand removal of medium and small sized castings, surface blast cleaning of forgings, heat-treated pieces, steel pipes, sections and steel structures, surface treatment before painting,shot peening of work pieces.
