Stainless Steel Shot Versus Cast Steel Shot

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.

Why Media Choice Decides Whether The Part Rusts Carbon steel media on aluminium Embedded iron oxidises after the part leaves the line An acid pickling step has to be added to remove it Stainless or zinc media on aluminium Surface stays bright with no rust and no discolouration Acid treatment and rust removal are not needed Sukie states that after processing with stainless steel media the surface is bright and needs no further acid treatment, and that zinc media deburrs without wearing down the surface because it is softer than steel and denser than aluminium.

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.
