Steel Shot Blasting Abrasive Supplier
Cast Steel Shot for Shot Blasting & Peening
A Steel Shot To Suit Every Application
Steel shot blasting abrasive media, is available in a range of different hardness grades, from S70 to S780. Unlike steel grit, steel shot sizing convention is the larger the number, the larger the particle size, the smaller the number, the smaller the particle size. Steel shot is only available in a single hardness grade.
The largest consumption of steel shot is for use in automatic wheel blasting machines. These use a stream of abrasive falling on a rapidly spinning wheel with paddles (similar to a water wheel) to energize the shot and impel it onto the work surface. Wheel blast machines use steel shot predominately because of it being less aggressive on machinery. Wear in wheel blast machines when using steel grit is uneconomically high. If using steel grit is unavoidable, use the softest grade available – GP.

What Is Steel Shot Hardness?
Hardness is a resistance of metal to plastic deformation – usually by indentation. This term may also refer to a metal’s stiffness, resistance to scratching, abrasion or cutting etc. It is the property of a metal which gives it the ability to resist being permanently deformed, bent or broken when an external load is applied.
How Is Steel Shot Hardness Measured?
The most common hardness test applied for steel shot is the Rockwell Hardness Test. This is a hardness measurement based on the overall increase in depth of impression as a pre-described load is applied to the surface of the metal.
Types Of Steel Shot
Spherical steel in the fully heat-treated condition. With a uniform structure it provides optimum resilience and resistance to fatigue. When steel shot is used for the majority of wheel blast applications, its durability and resistance to impact fatigue gives maximum cleaning efficiency at the most economical cost. Suited to shot peening applications.
Sizes Of Cast Steel Shot
There are many different grades and sizes of steel shot available and the selection of abrasive is determined by:
• type of material being blasted
• the coating being removed (e.g. mill scale, old paint)
• what profile is required
• condition of surface being blasted
