Steel abrasives are steel particles that are used as abrasive or peening media.[1] They are usually available in two different shapes (shot and grit) that address different industrial applications.
Steel shot refers to spherical grains made of molten steel through an atomization ("granulation") process, available in different sizes and hardnesses.
Steel grit characterizes grains with a predominantly angular shape. These grains are obtained by crushing steel shot, therefore they exhibit sharp edges and broken sections. Harder than steel shot, it is also available in different sizes and hardnesses.
