Popis:	The results of abrasion-resistance tests that were carried out on cast steel containing 1,1 % C, 16 % Cr, and 0,89 % Mo after several variants of heat treatment (including freeze hardening at -70 °C immediately before tempering at 200° and 550 °C) are presented in this paper. The wear-resistance tests were carried out with the ball-on-disc dryfriction method. In the samples that were tempered at 200 °C (with and without freezing), lower mass losses were obtained than in the samples that were tempered at 550 °C. Additionally, it was found that the applied freezing procedure significantly contributed to the reduction of mass losses in those samples that were tempered at both temperatures.
