Investigation of the Tribological and Mechanical Properties of Boron Steels in Terms of Potential Usage in Agricultural Applications

Abstract

Boron steels are increasingly used material especially in industrial applications requiring high wear resistance. The main area of usage of this type of steel is tillage tools which are working in harsh conditions. In addition to the abrasive wear resistance, impact toughness is also required properties. In this study, the effect of cryogenic treatment on 30MnB5 boron steel used in agricultural mechanization is investigated in terms of the tribological and mechanical properties. Charpy impact test, the hardness and the abrasive wear tests are performed on untreated, heat treated and cryogenically treated of 30MnB5 steel. It is observed that the hardness of the specimen is slightly decreased but impact toughness is increased for the quenched and cryo treated specimen in comparison to conventionally heat-treated specimen.
