Abstract

In the industrial world, there are many complex problems regarding metals, therefore it is necessary the existence of various variations of heat treatment on the metal in order to obtain a product that is in accordance with the desired desired. Therefore, this study was conducted to obtain data on the effect of treatment heat on the hardness value of Amutite steel and the effect of the hardening process with three types of media additives, namely carbon powder, anthracite, and wood charcoal with four variations of cooling media, namely Plain Water, Sea Water, Ice Water and Oil. With this research is also expected to be useful in manufacturing industry. The aim of the study was to obtain the optimum hardness value due to of the heat treatment and rapid cooling process. K-460/ AISI 01 amutite steel material is included in classification of tool steel used in the manufacturing industry to assist the production process such as cutting tools and as a mold material for plastic materials. Based on the results of research that has carried out it can be concluded that amutite steel or AISI 01 has a hardness of 16.3 HRC without treatment. The hardness of this amutite steel can be increased by heat treatment by cooling fast. Heat treatment carried out with the addition of activated carbon media is harder compared to with the addition of anthracite media and wood charcoal media. The highest violence is influenced by by the shape or dimensions of activated carbon which is finer than other media, where the more The finer or smaller the dimensions of the additive, the faster the diffusion process will occur. Where The average hardness for the addition of activated carbon media is Seawater (64.13), Ordinary Water (63.46), Oli (63.83), and Ice Water (66.2) with HRC units, while for anthracite media, namely Seawater (58.26), Ordinary Water (54.76), Oil (51.8), and Ice Water (55.8) with HRC units and Wood Charcoal media as big as Water Sea (58.33), Ordinary Water (51.83), Oil (45.8), and Ice Water (58.8) with units of HRC.
