The invention discloses abrasion-resistant steel, comprising the following chemical components in mass percent: 0.35-0.40% of carbon, 0.60-0.80% of silicon, 1.5-2.0% of manganese, 1.5-2.0% of chromium, 0.3-0.4% of nickel, 0.3-0.4% of molybdenum, less than or equal to 0.03% of phosphorus, less than or equal to 0.03% of sulphur, and the balance of iron. The abrasion-resistant steel of invention improves the content of manganese and chromium because of adopting the above technical scheme, and adds nickel to replace the original material ZG35CrMo, thus improving the hardness of the materials and prolonging the service life of the product.
Description
technical field [0001] The invention relates to a wear-resistant steel. Background technique [0002] Wear is one of the main forms of failure of metal mechanical parts. As an alloy steel widely used in various wear conditions, wear-resistant steel occupies an important place in materials science. Commonly used wear-resistant steels such as ZG35CrMo have the disadvantage that sometimes individual hardness is on the low side. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a wear-resistant steel, which increases the hardness of the material and prolongs the service life of the product. [0004] In order to solve the above technical problems, the present invention adopts the following technical scheme: wear-resistant steel, containing the following chemical components in mass percentage: carbon 0.35-0.40%, silicon 0.60-0.80%, manganese 1.5-2.0%, chromium 1.5-2.0%, nickel 0.3-0.4%, molybdenum 0.3-0.4%, phosphorus ≤ 0.03%,...
