The objective of this work is to determine the effect of various microstructural features on the wear of a high strength low alloy steel containing Mn, Cr, Ni and Mo. The wear performance of this newly developed steel is compared with that of a commercially available wear resistance steel (Hardox 400) in dry sliding against AISI 52100 hardened steel disk. The tests are run in the air at a normal load ranging from 50 to 85 N with a sliding velocity of 0.5 m/s. It is found that the wear rate (0.001-0.0025 mm3/m) of the pin specimen of the high strength low alloy steel is one-third of the Hardox 400. The analysis of the worn surface indicates that ploughing, delamination and oxidation are the main wear mechanisms. The work hardening as well as improved mechanical properties of the high strength low alloy steel lead to a superior wear performance.
