摘要

The characteristics of each component of a different aircraft such as the hexagonal bolt which functions to combine several components into one part that has a non-permanent nature. This requires that the component must be heat resistant, corrosion, and high hardness, to determine the microstructure and chemical composition of the hexagonal bolt then testing. This study uses quantitative research methods, namely the use of some quantitative data obtained from the test results to be processed in a table with the results of testing Micro structure and Chemical Composition on the hexagonal bolt. Microstructure testing on hexagonal bolt components is shown to be more dominant in the pearlite phase than the ferrite phase. The chemical composition of the hexagonal bolt shows that Iron (Fe) = 97,0%; Carbon=0,445%; Manganese (Mn) = 0,884%; Chromium (Cr)= 0,479%; Silicon (Si)= 0,241%; Molybdenum (Mo)= 0,201%; and Nickel (Ni)= 0,357% are medium carbon steel. The microstructure testing and chemical composition in hexagonal bolt components material has high heat resistance, corrosion resistance, and has a high hardness because more pearlite phases and the composition of iron (Fe) and manganese (Mn) that form material properties. Manganese (Mn) has corrosion resistance properties, increases material strength, and makes component durable. Therefore the strength of the hexagonal bolt is very important and the addition of several elements that help the properties of the main element. The correlation between microstructure and chemical composition is that the higher the Fe content, the higher the ferrite and pearlite microstructure because hexagonal bolt has a composition of 97% Fe which is hard, ductile, and a good conductor. We can be seen from the hexagonal bolt microstructure containing ferrite and pearlite which are the same as Fe.
