Abstract

Mild stell is low carbon steel contain 0,3 % carbon, for example ST 37. the mechanic properties hardness, tensile strength, tougness etc depend on carbon contain. In realty the weakness of ST37 are difficult to hardening. To increase hardness of mild steel are done heat treatment at 800 °C and 100 °C temperature. After that are hold for 30 minutes and then are quenched in oil SAE 10 and water for 15 minutes. For measuring hardnees of sampl are Brinell Methode. The result of testing the sample are obtained data like this, for heating 800 °C quench water the hardnees increase about 23,23 % and quench oil SAE the hardness decrease 28,54 %. When are heated 1000 °C the hardness both of sample decrease finally, in this experiment can be taken conclusion that mild steel are difficult to be hardening.
