Abstract
The invention provides high-speed steel containing chromium. The high-speed steel containing chromium comprises, by mass, 0.7% to 0.8% of carbon, 15% to 16% of tungsten, smaller than or equal to 0.3% of Mo, 3.8% to 4.4% of chromium, 1% to 1.4% of vanadium and the balance iron element, Al and Co. In the quenching process, the high-speed steel needs to be heated to the temperature between 550 DEG C to 570 DEG C and the temperature is kept for 2 h to acquire intergranular precipitation; and the high-speed steel is then heated to the temperature between 900 DEG C to 1000 DEG C, so that even austenite particles are acquired.
Description
Technical field
The present invention relates to a kind of rapid steel containing chromium, 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 containing chromium, 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 containing chromium, 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 15%-16%, Mo is less than or equal to 0.3%, and the massfraction of chromium is 3.8%-4.4%, the quality of vanadium divides 1%-1.4%, and all the other are ferro element and Al and Co; When quenching, by the heating temperatures of rapid steel between 500 DEG C-550 DEG C, insulation 2h obtains intergranular precipitation and separates out; Rapid steel is being heated between 900 DEG C-1000 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
