Abstract

The usage amounts of boron steels are increasing gradually, especially in industrial applications requiring high wear resistance. One of the usages of this type of steel is tillage tools, which are working in harsh conditions. Prominent desired properties for materials that face the soil in agricultural machining are hardness, abrasive wear resistance, impact toughness. In this study, the tribological and mechanical properties of 30MnB5 boron steel used in agricultural mechanization are investigated, applying three different heat treatment procedures. The impact strength, hardness and abrasive wear resistance of the as supplied, quenched and quenched cryo treated-tempered samples are evaluated. It was observed that the quenching is an essential heat treatment for usage of boron steel in agricultural field. The tempering reduces hardness of the specimen and cyrogenic treatment and tempering increased the impact toughness.
