Cast Steel Grit G*0,G*2,G*4,G*6,G*8,G*5,G*1,G*0,G*0,G**0The cast steel grit divided into three types, having been different in hardness. They are GP cast steel grit GL cast steel grit GH cast steel grit. Chemical Composition: C, Mn, Si, S, P Hardness: GP ****0HRC GL ****0HRC ****6HRC Microstructure: Tempered Marten site of Sorbite Density: 7.6g/cucm Angular when new, this grit rapidly rounds off in use and is particularly suited to removing sand of casting and scaling oxide. The cast steel grit divided into three types, having been different in hardness. They are GP cast steel grit GL cast steel grit GH cast steel grit. Although GL harder than GP steel grit, GL also loses its sharp edges during shot blasting and is particularly suited to decaling and surface preparation applications. GH always remains angular in its operating mix. These abrasive are particularly effective in surface treatment processes and produce a uniform, etched finish. GH angular grit should only be used in wheel machines where working requirements take precedence over cost price considerations.
