Description

Steel Shot is predominantly used in wheel blasting machines to remove millscale, peen surfaces or prep steel for coating.  In the foundry industry airless wheel blast machines like those made by wheelabrator are used to clean foundry castings and for surface finishing to impart a more polished surface to metallic objects. Also found in preservation lines in Steel Mills to remove milscale before applying a shop-primer.

Standard Steel Shot is GS Hardness which falls within 40-51 HRc (Rockwell Hardness).
Harder Steel shot is available for special applications, but you will need to call us for more details.

The industry Standard is SAE J827 which lists the allowable & of deformities in a defined sample of shot. Such deformities, in excess of this % reduce the durability and increase operating cost.

When shot peening, it is critical and essential to actually create a dent in the surface, this means that the steel shot must be spherical. it is critical that you choose the right grade of steel shot, to ensure you get consistent and repeatable shot peening results.
