Abstract

The report will cover research on of hardness, tensile and compression test before carburizing (Phase 1 ), carburizing-annealing (Phase 2), and carburizing-quenchingtempering (Phase 3) processes. Estimated better mechanical properties result of carburized specimens was expected compare to uncarburized specimens. The effect of carburizing on the mechanical properties of steel is important in terms of use. The carburizing treatment on low alloy steel shows brittle behavior. According to compressive results, percentage difference in compressive strength values are - 7.3% (from Phase 1 and Phase 2) and 26.41 % (from Phase 1 and Phase 3) meanwhile, the maximum load differs by -22.41% (from Phase I and Phase 2) This carburizing method more suitable for low carbon steel compared to low alloy steel. According to compressive test result _for low carbon steel, the maximum load) ncrease about 30.78% (Phase I and Phase 2) and + 33.32% (Phase I and Phase 3). And compressive strength value decreases to I4.66% (Phase I and Phase 2), 4I% (Phase I and Phase 3).
