Problems solved by technology

However, because it uses a pure martensitic matrix as a wear-resistant material, although the hardness is high, 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 medium-carbon high-chromium high-boron wear-resistant steel and a preparation method thereof. The prepared wear-resistant steel comprises, by weight percentage, 0.36-0.55% of carbon, 1.50-3.00% of silicon, 0.80-3.00% of manganese, smaller than 0.04% of phosphorus, smaller 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 Fe. The obtained wear-resistant steel is high in hardness, good intoughness and resistant to wear.

Description

technical field [0001] The invention relates to the technical field of alloy steel manufacture, in particular to a medium-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,...
