Stainless Steel Shot Versus Cast Steel Shot
Why abrasion resistance 3 to 5 times higher can lower the cost per treated part even at a higher price per kilogram.
The Number That Changes The Argument
Abrasion resistance of stainless steel shot is 3 to 5 times greater than cast steel shot. Sukie states this directly, and adds that it reduces producing cost. Media is bought by the kilogram but consumed by the cycle, so the price per kilogram is not the cost.
The Second Number Is The Step You Delete
Carbon steel media leaves iron on a non-ferrous part. That means an acid pickling line, the chemistry to run it and the effluent to treat. After stainless media the surface is bright and needs no further acid treatment.
Where Cast Steel Shot Still Wins
On plain steel work where iron pick-up does not matter and volumes are large, carbon steel media is the economic choice, which is why Sukie produces Carbon Steel Cut Wire Shot As Cut and Carbon Steel Cut Wire Shot Conditioned alongside the stainless ranges.
Comparing The Two Stainless Routes
Cast Stainless Steel Shot is atomized, round from the start, and runs 0.05 mm to 1.2 mm, which reaches finer than the cut wire route. Stainless Steel Shot Conditioned is drawn, cut and rounded, runs 0.2 mm to 2.5 mm and carries the 300 to 600 HV hardness figure. Both leave the surface bright.

Frequently Asked Questions
Where do the figures in this guide come from
Every size, hardness, density and chemistry figure is taken from the specification Sukie publishes for its own products, so it matches what would be shipped.
Can you advise on a case that is not covered here
Yes. Send the part material, the current media, the finish you need and the machine type and we will recommend the alloy, shape and grain size.
Do you supply samples
Send the alloy, shape and grain size you want to trial on WhatsApp or by email and we will confirm what we can send.
