Abstract

Abstract

In this paper, the samples of HRB335 screw steel containing vanadium were prepared, and the microstructure, mechanical properties and wear resistance of the samples were tested, compared and discussed. The results show that with the increase of vanadium content, the mechanical properties and wear resistance of the samples increase first and then decrease, and the internal structure of the samples is refined and the pearlite lamellae spacing decreases, while the pearlite lamellae are not straight at the vanadium content of 0.05%. Compared with the samples without vanadium, the tensile strength and yield strength of the sample with 0.04% vanadium respectively increase by 4.8% and 3.9%, with the wear volume decreased by 28.95%. The optimal content of vanadium in the steel sample is at 0.04%.
