S less than 0.05% P less than 0.05%
2, Average hardness ( 500g loading )
GP: 42-50HRC (399-509HV)
GL : 56-60HRC (620-713HV)
GH: 63-66HRC (795-889HV)
3, Hardness deviation: Max deviation 3.0HRC (40HV)
4, Metallography structure: Even tempered martensite and dispersed carbon
5, Min density(Alcohol replace testing) : 7.4g/cm3
6, High strength, long lasting Ervin life: Cast steel grit: 2200 cycles
GP: Angular when new, this grit rapidly rounds off in use and its particularly suited descaling applications.
GL: Although harder then GP steel grit, also loses its sharp edges during shot basting and is particularly suited to descaling and surface preparation applications.
GH: Having maximum hardness, 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 (for example with rolling mill cylinders or when a special finish is needed). For use mainly with compressed air equipment.
