STEEL SHOT

​

Sigma Steel Shot is manufactured to the SAE J827 Specification for chemistry, hardness and other characteristics and the SAE J444 Specification for sizing. 

​

• Cast steel shot is spherical.

​

• The product is fully heat-treated and supplied in the quenched and tempered condition. This makes the product very durable with a high resistance to fatigue, allowing for optimal cleaning efficiency.

​

• Steel shot is ideally suited for wheel blast applications because it is a round product that stays mostly round throughout its working life. This reduces the wear on the wheel blast machines as compared to using steel grit. 

​

• Steel shot cleans by repeatedly pounding the surface. As the steel shot impacts the surface, it ricochets off the work piece and surrounding structures giving multiple impacts to the surface. This increases the potential for the shot to impact areas of the work piece that would normally be inaccessible to direct line of sight blasting.

​

• The microstructure for Sigma high carbon steel shot is uniform Martensitic tempered to a degree consistent with the hardness range.
