Abstract
The invention relates to a high wear resistance blade material. The high wear resistance blade material comprises the following components in percentage by weight: 0.35% of tungsten, 1.2% of carbon, 0.3% of vanadium and the balance of steel. The high wear resistance blade material has the beneficial effects that tungsten carbide formed by tungsten and carbon after adding W (tungsten) has high hardness and wear resistance, so that the red hardness and heat resistance can be remarkably improved by adding tungsten in high-carbon steel.
Description
Technical field
The present invention relates to a kind of blade, relate in particular to the material of this blade.
Background technology
Blade material generally is comprised of C (carbon), Fc (iron).
Because lacking W (tungsten) content, reduced the wear resistance of blade during use in the existing blade material, and the hardness of blade.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of high-wearing feature blade material, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention comprises by weight percentage: tungsten 0.35%, carbon 1.2%, vanadium 0.3% and surplus are steel.
Compared with prior art, the invention has the beneficial effects as follows: W (tungsten) after adding, tungsten and carbon form wolfram varbide very high hardness and wear resistance.Add tungsten at high carbon steel, can significantly improve red hardness and heat resistance.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail:
The present invention comprises by weight percentage: tungsten 0.35%, carbon 1.2%, vanadium 0.3% and surplus are steel.
Tungsten among the present invention: symbol of element W, silvery white metal, ordination number 74, nucleidic mass 183.84, fusing point are 3407 ℃, and boiling point is 5655 ℃, and density is 19.34g/cm
3(20 ℃).Tungsten and carbon form wolfram varbide very high hardness and wear resistance.In tool steel, add tungsten, can significantly improve red hardness and heat resistance, be used as cutting tool and forging mould.C (carbon) 1.2%, high carbon steel have good hardenability and wear resistance.V (vanadium) 0.3%: vanadium is the good reductor of steel.But add 0.3% vanadium thinning microstructure crystal grain in the steel, improve intensity and toughness.The carbide that vanadium and carbon form can improve anti-hydrogen-type corrosion ability under High Temperature High Pressure.
The present invention adopts and to contain: the carbon steel of W (tungsten), V (vanadium), and by in solid-state lower heating, insulation and cooling, the interior tissue of change steel.Through quench, after the tempering, make the blade material surface hard and wear-resisting, improve the hardness of steel, intensity keeps good plasticity and toughness simultaneously.
