TL;DR: In this article, two commercial cold work tool steels, AISI D2 and O1, were heat treated in order to obtain the same hardness 700-HV (60-HRc) and were subsequently tested in three different modes of wear, namely in adhesion, three-body and two-body abrasion, by using pin-on-disk, dry sand/rubber wheel apparatus and pin-abrasion on SiC, respectively.
