Steel blasting media has actual steel material paired with numbered grit choices from 20 to 170. The body model says S390, grain size reads 0.1–3mm, and the shape is angular.
The title shot size labels need a selected grading specification rather than assumed conversion to the numbered options. Confirm whether angular particles meet the requested shot geometry. Hardness 40–50 and density 7.4 lack explicit units or scales in this record.
For polishing or shot-peening trials, provide equipment, workpiece and surface acceptance. No intensity, coverage or reuse test is supplied. Request particle-size, shape and material inspection documents; the SGS certificate label and general quality wording do not establish an approved peening process or a validated service life.
