摘要
The invention relates to a method for producing rust-resistant, angular shot-blasting abrasives (60 HRC) based on a Fe-Cr-C alloy. According to said method, a granulate consisting of an iron-chrome-carbon alloy is tempered to 60 HRC by subjecting it to a thermal treatment of greater than 900° Celsius in a reduced atmosphere. A stainless, hard material which can be reduced to angular granules is thus produced. This results in shot-blasting abrasives with excellent characteristics for treating the surface of workpieces consisting of stainless material, e.g. stainless steel, non-ferrous metal and natural stone.
