Abstract

The invention provides high-speed steel which is prepared from the following components in percentage by mass: 0.7-0.8% of carbon, 17.5-19% of tungsten, less than or equal to 0.3% of Mo, 3.8-4.4% of chromium, 1-1.4% of vanadium and the balance of iron, Al and Co; during quenching, the high-speed steel is heated to 550-570 DEG C and then intergranular precipitation is separated out after the temperature is kept for 2 hours; and when the high-speed steel is further heated to 1100-1300 DEG C, crystal particles with uniform austenite are obtained. The high-speed steel provided by the invention is relatively high in hardness and toughness and surface grains are uniform and fine in; and further a high-quality high-speed steel turning tool can be manufactured.

Description

A kind of rapid steel
Technical field
The present invention relates to a kind of rapid steel, belong to field of mechanical technique.
Background technology
Existing rapid steel uses as lathe tool, drill bit etc. needs high surface hardness, high tenacity, surface particles even, as high quality lathe tool, is badly in need of a kind of method obtaining this rapid steel.
Summary of the invention
The invention provides a kind of rapid steel, hardness toughness is all higher, and surface particles uniform and smooth, high quality High Speed Steel Lathe Tool can be obtained.
For solving above technical problem, the invention provides following technical scheme: a kind of rapid steel, comprise carbon, tungsten, Mo, chromium, vanadium, the massfraction of described carbon is 0.7%-0.8%, the massfraction of tungsten is that the massfraction of 17.5%-19%, Mo is less than or equal to 0.3%, and the massfraction of chromium is 3.8%-4.4%, the massfraction 1%-1.4% of vanadium, all the other are ferro element and Al and Co; When quenching, by the heating temperatures of rapid steel between 550 DEG C-570 DEG C, insulation 2h obtains intergranular precipitation and separates out; Rapid steel is being heated between 1100 DEG C-1300 DEG C, is obtaining the uniform crystal grain of austenite.
This rapid steel that the present invention relates to, hardness toughness is all higher, and surface particles uniform and smooth, high quality High Speed Steel Lathe Tool can be obtained.
Embodiment
A kind of rapid steel, comprise carbon, tungsten, Mo, chromium, vanadium, the massfraction of described carbon is 0.7%-0.8%, the massfraction of tungsten is that the massfraction of 17.5%-19%, Mo is less than or equal to 0.3%, and the massfraction of chromium is 3.8%-4.4%, the massfraction 1%-1.4% of vanadium, all the other are ferro element and Al and Co; When quenching, by the heating temperatures of rapid steel between 550 DEG C-570 DEG C, insulation 2h obtains intergranular precipitation and separates out; Rapid steel is being heated between 1100 DEG C-1300 DEG C, is obtaining the uniform crystal grain of austenite.
This rapid steel that the present invention relates to, hardness toughness is all higher, and surface particles uniform and smooth, high quality High Speed Steel Lathe Tool can be obtained.
Embodiment of the present invention does not form the restriction to the application's scope; within every spirit in the present invention's design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection scope of the present invention.
