However, since it uses a pure martensitic matrix as the wear-resistant material, although the hardness is high enough, the wear resistance is insufficient. For the crushing of ferrochrome slag and steel slag, its wear resistance is far from enough

Abstract
The invention discloses micro-carbon high-chromium high-boron wear-resistant steel and a preparation method thereof. The prepared wear-resistant steel comprises the following components of, in percentage by weight, 0.10-0.25% of carbon, 1.50-3.00% of silicon, 0.80-3.00% of manganese, less than 0.04% of phosphorus, less than 0.04% of sulfur, 9.00-15.00% of chromium, 0.30-3.00% of nickel, 0.10-1.00%of molybdenum, 0.10-0.50% of vanadium, 0-1.50% of tungsten, 0.01-0.10% of titanium, 0.40-0.80% of boron, 0.10-0.40% of copper, 0.10-0.30% of aluminum, 0.02-0.25% of niobium, 0.02-0.10% of zirconium,0.10-0.50% of cerium, 0.01-0.15% of tin, 0.001-0.003% of magnesium, 0.001-0.15% of calcium, 0.003-0.025% of nitrogen, 0.001-0.005% of rhenium, and the balance iron. The steel not only has the high hardness, also has the characteristics of certain toughness and high wear resistance at the same time.
Description
technical field [0001] The invention relates to the technical field of alloy steel manufacture, in particular to a micro-carbon high-chromium-high-boron wear-resistant steel and a preparation method thereof. Background technique [0002] Alloy steel is an iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements to ordinary carbon steel. According to the different elements added and appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and non-magnetic properties can be obtained. [0003] Alloy steel can be divided into low alloy steel, medium alloy steel and high alloy steel according to the content of alloy elements in the steel. The main alloying elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, ra...
