Steel blasting abrasive, angular
Angular cast steel (STEEL GRIT) pur­suant DIN ISO 11124–3

Angular grain (steel grit) is pro­duced by breaking a material with a similar che­mical ana­lysis as that of the sphe­rical material (steel shot). Com­pared to round abrasive, angular material has a higher abra­si­veness due to the broken sharp edges.
This abra­si­veness is necessary for some blasting tasks (e.g. roller roughening, surface roughening for spray gal­va­nising) despite the resulting increased equipment wear.
