Improvement of wear resistance of some cold working tool steels

We have investigated two tool steels, Sverker 21 (AISI D2) and Vanadis 6. The former belongs to traditional steels, the latter is classified as advanced powder metallurgy (P/M) alloyed steel. We have performed pin-on-disc tribological experiments to determine abrasive friction and wear. Our evaluation of tribological properties of these two cold working steels enables an improvement of their manufacturing procedures leading to significant wear reduction. The improvement proposed is applicable not only to tool steels.118
