Abstract
The invention relates to tool steel for a saw blade of an electric saw. The tool steel comprises the composition by the weight percentage: 1.8-2.2% of carbon, 0.5-0.65% of silicon, 3.8-4.0% of chromium, 3.0-4.0% of molybdenum, 1.0-1.5% of vanadium, 5.0-8.0% of tungsten, 0.001-0.003% of niobium, 0.5-1.2% of cobalt, 0.1-0.3% of copper, 0.1-0.3% of boron, 0.03-0.05% of zirconium, and the balance being iron and unavoidable impurities. While the tool steel is ensured to have high hardness and high wear resistance, the tool steel brittleness is reduced and the tool steel is ensured to have a certain toughness.
Description
Technical field
The present invention relates to a kind of tool steel, refer to especially a kind of a kind of electric saw saw blade tool steel that adopts powder metallurgy technology to produce.
Background technology
Since powder metallurgy technology exploitation, the tool steel that adopts powder metallurgical technique to produce can be removed the impurity in steel, can improve the toughness of material and can improve the brittle behavior of tool steel.And the powder metallurgical technique tool steel of producing can realize the tool steel of the high alloy content that existing cast forging process cannot produce.
In the tool steel of the high alloy content that existing powder metallurgy is produced, in order to improve the hardness wear resistance of tool steel and the toughness of appropriateness, use in a large number precious metal element, make the cost of tool steel higher.Now also there is technology proposition, adopted some unit that price is low usually partly to substitute precious metal element, but still do not reach the performance of the tool steel of using precious metal production, therefore need to improve.Particularly for the use of cobalt element, although cobalt element add the hardness that can improve tool steel, but increased the fragility of tool steel and reduced plasticity-, and the effect of manganese element in iron alloy when manganese identical with the effect of cobalt during at certain content, but with other element, coordinate and can guarantee that hardness has again certain toughness, be conducive to improve the work-ing life of tool steel.Therefore the improvement, material being formed completely likely realizes.
Summary of the invention
The object of the invention is to propose a kind of technical scheme of powder metallurgy means of production steel, by the technical program, on the basis reducing costs, there is the powder metallurgy tool steel of high rigidity, high-wearing feature and low fragility.
The present invention is achieved by the following technical solutions:
A kind of electric saw saw blade tool steel, its composition is by weight percentage, the carbon of 1.8-2.2%, the silicon of 0.5-0.65%, the chromium of 3.8-4.0%, the vanadium of the molybdenum of 3.0-4.0%, 1.0-1.5%, the niobium of the tungsten of 5.0-8.0%, 0.001-0.003%, the copper of the cobalt of 0.5-1.2%, 0.1-0.3%, the zirconium of the boron of 0.1-0.3%, 0.03-0.05%, surplus is iron and the impurity do not avoided.
As further improvement, described electric saw saw blade tool steel, its composition is by weight percentage, the carbon of 2.0-2.2%, the silicon of 0.5-0.65%, the chromium of 3.8-4.0%, the tungsten of the vanadium of 1.0-1.1%, 6.5-7.5%, the cobalt of the niobium of 0.001-0.0015%, 0.8-1.0%, the boron of the copper of 0.1-0.3%, 0.1-0.3%, the zirconium of 0.03-0.05%, surplus is iron and inevitable impurity.
Described preparation method is identical with conventional powder metallurgical production technique, included, batch mixing, be pressed into base, refining, vacuum atomizing, hot static pressure, forge, finishing obtains finished product.
The present invention's beneficial effect is compared with the existing technology:
Guaranteeing tool steel high rigidity, high-wearing feature simultaneously, reduced the fragility of tool steel and guaranteed that tool steel has certain toughness.
