Abstract : In this work the effect of shallow cryogenic treatment (SCT) on mechanical properties of AISI 1018 steel were studied. Experimental studies were conducted on the carburized, shallow cryogenic treated and untreated AISI 1018 steel specimens. Carburizing is done at 9200°C, kept at that temperature for 10 hours. Shallow cryogenic treatment (-770°C) is performed on carburized specimen in order to improve mechanical properties. Mechanical properties like tensile, hardness, wear test were performed, it shows improved results on shallow cryogenic treated and case carburized steel material compared to untreated material and non-carburized material. This is due to transformation of some amount of retained austenite (in carburized specimen near case alone) to martensite. © Research India Publications.
