Low alloy medium carbon steels have tremendous potential for agricultural application because of its low cost and obtaining excellent combination of various properties after heat treatment. In the present study abrasive wear response of medium carbon steel used for soil working components of agricultural implements i.e. rotavator blade, cultivator sweep, plough share etc. was studied under three heat treatment processes and three load conditions. Micro structural, mechanical, and tribological properties of medium carbon SAE-6150 steel were altered by annealing, intercritical annealing and quenching and tempering heat-treatment processes. A rotating rubber wheel type test apparatus was used to measure the wear rate of heat-treated and control specimen at 75, 200 and 375 N loads. This technique of wear measurement is very similar to working condition of soil working components of agricultural implements. The study revealed that under low load (75 N) condition, both the intercritically annealed and quenched and tempered SAE-6150 medium carbon steels gave identical wear resistance. However, inter-critically annealed material under medium load (200 N) condition and quenched and tempered material under high load (375 N) condition exhibited supremacy in terms of abrasive wear resistance.
