Abstract

This research covered mainly the effects of heat treatment on mild steel (A36). Three types of heat treatment are annealing, quenching and tempering. There are two types of specimen being used consisted of cylinderical with dimension of 25 mm x 50 mm and square shape, 320 mm x 40 mm x 3 mm. During annealing process, specimen are annealing at the 850°C at different time before taken out from furnace. These specimen then are quenched in oil and being reheated again for tempering process at 450°C. The quenching process is using three types of medium which are oil, air and water. The tempering process consists the two parameter are time and temperature will be considered. Both produces the different result as comparison. After the process completed, three types test will be conducted which are hardness, microstructure and tensile test on the specimen. The hardness test applied Rockwell (B) with the con diamond. In term of microstructure observation, Axoiskop 2 Mat and CCTV are used as the main medium to obtain the result. The tensile test applied the Universal Testing Machine (UTM) which are prepare two specimen for one data. These result then compare the related industrial result which are based on the handbook. The expected result for microstructure test for annealing, quenching and tempering are fine pearlite, lath martensit dan spherodite respectively.
