Embodiment Construction
[0039] The present invention will be further described below in conjunction with the embodiments, and the embodiments of the present invention can be used to illustrate the principle of the present invention.
[0040] The invention relates to a high-strength toughness high-hardenability high-speed axle steel, the chemical composition of which contains C, Si, Cr, Mn, V, Nb, B, Ni, Mo, Alt, P, S, O and N, And Fe and unavoidable impurities.
[0041] Preferably, the C content is 0.24 to 0.32wt.%. Carbon is one of the most important strengthening elements and elements that improve hardenability. In order to ensure sufficient strength and hardenability, the C content must be above 0.24wt.%. However, when the C content is higher than 0.32wt.%, the plasticity and toughness of the steel will be significantly reduced.
[0042] Preferably, the content of Si is controlled to a relatively low level of 0.20-0.40wt.%. Si is an alloying element that has a significant solid solution strengthe...
