Abstract

Bucket teeth on excavators are essential components used for digging and loading materials. Consequently, the material used must possess high wear resistance, hardness, and toughness. Manganese steel is commonly used for this purpose because of its exceptional wear resistance. This research aims to enhance the wear resistance of bucket teeth through heat treatment. The material used in this study was manganese steel containing 16.86%wt Mn. Various heat treatment including austenitization at a temperature of 1050℃ followed by quenching, tempering, normalizing, and annealing. The tests conducted included Vickers hardness, wear rate, and microstructure observation using a metallurgical microscope. The annealing increases hardness by up to 33% and wear resistance by up to 50% compared to the as-cast condition, due to the formation of manganese carbides at the grain boundaries. The quenching decreases hardness and wear resistance by up to 27% and 66% compared to the as-cast condition, attributed to the formation of a stable austenite structure with a grain size of 60-80 µm. The tempering and normalizing do not increase hardness or wear resistance compared to the as-cast condition. Therefore, the annealing is recommended to improve the mechanical properties of manganese steel as a material for excavator bucket teeth.
