Abstract
The invention relates to the technical field of preparation of wear resistant cast steel and discloses wear resistant cast steel and a preparing method thereof. The wear resistant cast steel comprisesthe following chemical components: C, Si, Mn, Cr, S, P, Fe and trace elements, and the mass percents of the C, Si, Mn, Cr, S and P are 0.03-0.04 of C, 0.005-0.006 of Si, 0.27-0.3 of Cr, 0.004-0.005 of Mn, 0.0003-0.0005 of S and 0.0003-0.0005 of P. According to the wear resistant cast steel and the preparing method thereof, by the reasonable chemical components and thermal treatment process, the cheap Si, Mn and Cr elements are adopted without adopting the heavy alloy elements such as Ni, Mo and Co, the production cost is low, the wear resistance of the wear resistant cast steel is greatly improved by the preparing method from steps 9) to 12), meanwhile, the surface compactness of the wear resistant cast steel is improved, the wear resistance and corrosion resistance are enhanced, and thewhole preparing method is simple to operate and can be further popularized and applied.
Description
technical field [0001] The invention relates to the technical field of preparation of wear-resistant cast steel, in particular to a wear-resistant cast steel and a preparation method thereof. Background technique [0002] Cast steel is a general term for iron-based alloys used to produce castings that do not undergo eutectic transformation during solidification. Cast steel is divided into three categories: cast carbon steel, cast low alloy steel and cast special steel. For machine parts with higher requirements on strength, plasticity and toughness, steel castings are required. Existing cast steels have low yield strength, tensile strength, and low mechanical performance indicators such as impact resistance, which can no longer meet the requirements of products. Requirements for the mechanical properties of materials. At present, in the field of wear-resistant materials, most of the wear-resistant materials with martensite or bainite matrix structure or particle-reinforced ...
