S330 or S280 shot blasting media (Liquid Gravity)


Andy Carlson
 

"Shot blasting media" suggests to me that these miniature balls are for shot peening, an industrial process which smooths over minute surface "risers" on steel parts, such as crankshafts and connecting rods. Much like we notch a corner of a potato chip bag to start the tear to open the bag, stress risers are micro raised areas of a machined or forged surface where cracks can start and propagate to destruction. Metal media stuff is propelled at a very high velocity and has to be metal particles to achieve the desired results.

Part of an on-line review stated, "I am not sure what metal is used for the tiny little "BBs", but it is not magnetic and after a few measurements I came up with a density of about 4.15 gr/cm3 (lead has a density of 11.3 gr/cm3 for comparison)."

Disappointing that this product provides less weight than an equal volume of lead.
