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.

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.
