Abstract: An abrasive for jet cutting including particles of a stainless steel is provided, the stainless steel includes a microstructure, the microstructure including at least martensite, in a range of ?20 wt. % to ?100 wt. %, austenite in a range of ?0 wt % to ?50 wt %, and chromium carbide, chromium nitride and/or mixtures thereof, together in a range of ?0 wt % to ?45 wt % based on the microstructure, the proportions being selected such that together they amount to ?100 wt % based on the microstructure. The abrasives for jet cutting exhibit particularly good lifetime and recyclability. Also provided is a suspension for jet cutting including at least the proposed abrasive for jet cutting and a suspending agent, as well as the use of the abrasive for jet cutting for cutting a workpiece.

Abstract: A stainless blasting medium is provided including blasting medium elements containing an austenitic chromium-manganese steel, the blasting medium comprising the austenitic chromium-manganese steel-containing blasting medium elements in a range of ?90 wt.-% to ?100 wt.-% relative to the total weight of the stainless blasting medium. The following further relates to the use of the stainless blasting medium for blasting surfaces, metal and non-metal surfaces, such as workpieces, in particular stainless workpieces.
