description: SS 304 alloy steel is an austenitic stainless steel that has mechanical properties, namely tensile strength of   646 MPa, yield strength of 270 MPa, elongation of 50%, hardness of 82 HRB. The purpose of this research   is to determine the effect of heat treatment of stainless steel 304 thin foil which is heated to high   temperature and then tensile tested to determine the microstructure after cooling. As for the limitations of   the problem in this study, there are two variables, namely the independent variable and the dependent   variable. So that the independent variables are austenization temperature, tempering temperature, and   cooling process, then the dependent variable is grain size, microstructure, and tensile test on stainless steel   304 thin foil. Test samples that have been heat treated using a rapid cooling process (quenching). The   results showed that the microstructure looks like a needle or blade and has a black color and also has very   hard mechanical properties. Then the microstructure obtained from this test is the martensite phase where   this phase is formed by heating the sample to austenite temperature after which it is rapidly cooled   (quenching) using ice water. Furthermore, in this rapid cooling process there is no time for carbon to   diffuse out, so the transformation occurs when the atom shifts from face centered cubic (FCC) lattice to   body centered tetragonal (BCT). In the SUS 304 thin foil sample, the tensile test results with a grain size   of 1.5 μm have the smallest true stress value of 406 MPa, and have a true strain value of 1. The highest   tensile strength value is 571 MPa, the true strain value is 1.16. While the sample with a grain size of 3 μm   has a true stress value of 380 Mpa, then the true strain value is 1, while the highest tensile strength value   is 490 MPa, with a true strain value of 1.16.
