Abstract
The present invention relates to an abrasive for blast cutting, having particles consisting of a stainless steel, the stainless steel consisting of a microstructure, the microstructure at least containing: martensite, in particular 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.%, in relation to the microstructure, the percentages being selected such that they add up to ≤ 100 wt.% in relation to the microstructure. The abrasives for blast cutting have particularly good creep strength and reusability. The invention also relates to a suspension for blast cutting, containing at least the proposed abrasive for blast cutting and a suspending agent, and to the use of the abrasive for blast cutting for cutting a workpiece.
