Abstract
The invention provides a hard cutting tool steel. The hard cutting tool steel is characterized by being prepared from the following elements in percentage by weight: 0.15%-0.22% of C, 0.7%-0.9% of Mn, 1.0%-2.3% of Si, 0.1%-0.3% of Ni, 0.2%-0.5% of Ti, 0.6%-0.9% of rare earth, and the balance of Fe and inevitable impurities. The hard cutting tool steel has the beneficial effects of high strength, high hardness, corrosion resistance, wear resistance and high temperature resistance, and is suitable for working normally under a plurality of complex environments; a cutting tool produced by use of the hard cutting tool steel is long in service life and high in cost performance, and suitable for large-area popularization and application in the industrial manufacturing field.
Description
Technical field
The present invention relates to a kind of steel alloy, especially a kind of inserted tool steel.
Background technology
Steel is the core of cutter, finds more high performance material in people's steel.The character of steel itself determines one of cutting performance important determinative, traditional rapid steel is because having very high bending strength and impelling strength, and good workability, modern times are still most widely used cutter material, but still have the residual austenite of 25% ~ 35% after its quenching in tissue, cause speedy steel cutting-tool easily crack and corrode.Along with inserted tool has appearred again in development in science and technology, traditional inserted tool is mainly divided into two large classes, and one is tungsten cobalt alloy, and another is tungsten-cobalt-titanium alloy, but its cost of manufacture is very expensive, is therefore badly in need of a kind of new material and solves the problems referred to above.
Summary of the invention
The invention provides a kind of inserted tool steel.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of inserted tool steel, add each element according to weight percent meter, its composition is: C:0.15%-0.22%, Mn:0.7%-0.9%, Si:1.0%-2.3%, Ni:0.1%-0.3%, Ti:0.2%-0.5%, rare earth: 0.6%-0.9%, all the other are Fe and not removable impurity.
Described addition element according to weight percent is: C:0.16%-0.2%, Mn:0.6%-0.85%, Si:1%-1.8%, Ni:0.2%-0.3%, Ti:0.25%-0.6%, rare earth: 0.5%-0.7%, and all the other are Fe and not removable impurity.
Described addition element according to weight percent is: C:0.18%-0.2%, Mn:0.75%-1%, Si:1.2%-1.9%, Ni:0.15%-0.23%, Ti:0.18%-0.55%, rare earth: 0.45%-0.6%, and all the other are Fe and not removable impurity.
The invention has the beneficial effects as follows: work normally under high strength, high rigidity, corrosion-resistant, wear-resisting, high temperature resistant applicable various complicated, made cutter has the longer life-span, and its cost performance is high, the spread being applicable to industry manufacture field uses.
