【 摘 要 】

The development of Iron and steel is the fundamental essential needs for a construction. Indonesia should seek local raw materials for steelmaking production to cooperate with industrial markets. In this research, a new innovation in the manufacturing of bucket teeth components using laterite steel by optimizing the nickel alloy content reaches 1.5-3% and other alloys with special heat treatment process. The best results of optimization abrasion wear resistance and hardness properties on 1Cr1Mo steel with quenching oil treatment resulted in hardness of 43.60 HRC and had a good abrasive resistance of 0.16 gr/cm2 weight loss. In morphological analysis of microstructure showed that the grain boundaries become more flattened and sharpened into martensite phase transformation.
