Abstract
Steel produced by PT. Krakatau steel is the most used product in construction applications to compete with the other structural steel and have the minimum standard. PT. Krakatau Steel produced the steel with 0.08% carbon as JIS 3302 grade SGC 400 standards, resulting in low yield and tensile strength. This study aims to investigate the effect of temperature and the number of cycle spheroidizing on mechanical properties and microstructure. Steel with 0.08% carbon heated at 580, 650, and 720 °C for 6 minutes each cycle (3 cycles) and subsequently cooled by forced air with a 3 °C/s cooling rate. At a temperature of 580 °C on cycles 1, 2, 3, and 650 °C in the third cycle 3, resulting in mechanical properties that meet the JIS G 3302 grade SGC 400 standards.
