Omni Finishing - GP Steel Grit

Unit of Measure

Items	SGGP 12 GP Angular Shot	SGGP 14 GP Angular Shot	SGGP 16 GP Angular Shot	SGGP 18 GP Angular Shot	SGGP 25 GP Angular Shot
Description	N/A W Abrasives technical studies have shown that at an average of 44 HRC hardness, GP Angular-shot™ provides the optimum performance in many foundry and other cleaning applications. These studies show that the performance characteristics of GP Angular-shot™ are similar to steel shot but also have the extra initial aggressiveness of an angular material. Due to the rapid rounding of GP Angular-shot™ there is no increase in abrasive consumption or machine wear. New product would look similar to steel grit. Angular when new, this grit rapidly rounds off in use and is particularly suited to general cleaning applications.

Sieve analysis	N/A According to standard SAE J 444
Chemical analysis	N/A According to standard SAE J827 shot / J1993 grit
Micro Hardness	N/A 40 - 51 HRC
Victors	N/A 392 - 528 HV
Standard deviation	N/A ±3Rc or ± 240 HV
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.
Minimum Density Measured by Alcohol Displacement	N/A > 7.3 g/cm
