Description
K340 steel thanks to the high value of alloying elements and high mechanical properties is used for dies and punches in mint industry. In this work we tried to increase its properties via different heat treatments. A series of simulations and dylatometric measurements was made to determine optimal parameters of heat treatment. Then properties such as hardness, crack resistance, tensile strength, yield strength and impact toughness were measured, and microstructural observations were conducted on light and electron microscopes. New types of heat treatment were developed for this steel based on austempering and BQP (bainitisation- quenching-partitioning) process.
