High carbon steel shot
High carbon steel shot is used in the majority of the wheel blast applications and creates a dimpled, peened
surface.
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.
·Surface blast cleaning of small sized castings, forgings and heat-treated pieces, aluminium and copper alloy
castings, steel plates, steel pipes, sections and steel structures, shot peening of work pieces.
·Surface blast cleaning of stainless steel plates, thin steel plates, non ferrous alloys, dacromet coat.
