In the crushing pin-on-disk tests the construction steel S355 and stainless steel AISI 431 behaved almost similarly when using the same abrasive. Tool steel WR6 yielded clearly lower wear rates, as could be expected from its higher hardness. The abrasives as well as the used counterbody had a distinctive influence on the wear of the pin materials.
