Abstract

This work studies the outcome of heat treatment of AISI 4140 on wear, hardness, and tensile strength. The properties were compared after subject the specimen to annealing, normalizing, hardening and tempering. Amongst the methods used hardened specimen showed a hardness of RC45 and wear rate of near zero. Annealed specimen showed a Percentage Elongation of 15.56 and the tempered specimen had a tensile strength of 1109.4 N/mm2.
