Abstract

Steel pellets for use in blast cleaning and blast peening are made of a steel having the composition C 0.1-1.7 per cent; Si 0.3-1.0 per cent; Mn 0.3-2.0 per cent; Fe the balance. The alloy may also include one or more of the following elements: Cr up to 5.0 per cent; Mo up to 5.0 per cent; V up to 0.4 per cent; Ni up to 2.5 per cent; Cu up to 1.0 per cent.
