The invention relates to a process for producing acorrosion-resistant blasting agent ( 60 HRC) with sharpedges based on an Fe-Cr-C alloy. A granulate consisting ofan iron-chromium-carbon alloy is hardened in said process to 60 HRC by subjecting it to a heat treatment at above 900°Celsius under a reducing atmosphere. An oxide-free, hardmaterial is obtained in this way that can be crushed intograins with sharp edges. The result is a blasting agent withexcellent properties for the surface treatment of workpiecesconsisting of corrosion-resistant materials such as, forexample stainless steel, nonferrous metals and naturalstone.
