Abstract
The invention discloses a high-abrasion-resistant titanium alloy steel tube. The high-abrasion-resistant titanium alloy steel tube is composed of a major component and a minor component. The major component is prepared from, by mass, 40.0%-42.0% of Ti, 36.5%-38.5% of Cr, 9.5%-11.5% of Al and 5.5%-7.0% of W, the content of the minor component ranges from 4% to 5%, and the minor component comprises two or more of C, Si, Co, Mo and V. In this way, hardness, abrasion resistance and corrosion resistance of titanium alloy can be improved, the good impact property is achieved, and the titanium alloy is not prone to abrasion and disengagement.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of high wear resistance titanium alloy steel pipe.
Background technology
Titanium alloy tube is the pipe utilizing titanium alloy to make, and has higher mechanical property, excellent punching performance, and can carry out various forms of welding, and strength of welded joint can reach 90% of matrix metal intensity, and machinability is good.The advantage of titanium alloy is that specific tenacity is high, and corrosion resistance and good makes structured material at the wide hair of the industrial sector such as space flight and aviation and petrochemical complex, but to be hardness low, wear resisting property is poor for its shortcoming, when being used as pipe fitting, easy to wear.
Existing titanium alloy tube generally need adopt heat treated mode to improve its wear resisting property, make its surface have one deck wearing layer, but this layer of wearing layer in use easily comes off, thus affects its performance and use.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, provides a kind of high wear resistance titanium alloy steel pipe, can improve the hardness of titanium alloy, wear resistance and erosion resistance, make it have good impact property, not easy to wearly comes off.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of high wear resistance titanium alloy steel pipe, described high wear resistance titanium alloy steel pipe is made up of main component and submember, described main component comprises the following ingredients formed by mass percentage: Ti:40.0%-42.0%, Cr:36.5%-38.5%, Al:9.5%-11.5%, W:5.5%-7.0%, the content of described submember is 4%-5%, and it is two or more that it comprises in C, Si, Co, Mo, V.
In a preferred embodiment of the present invention, described high wear resistance titanium alloy steel pipe comprises the following ingredients formed by mass percentage: Ti:40.2%, Cr:37.8%, Al:11.3%, W:5.9%, C:0.45%, Si:0.85%, Co:3.2%, V:0.3%.
In a preferred embodiment of the present invention, described high wear resistance titanium alloy steel pipe comprises the following ingredients formed by mass percentage: Ti:41.7%, Cr:36.9%, Al:10.8%, W:6.3%, C:0.37%, Si:0.73%, Co:3.0%.
The invention has the beneficial effects as follows: mated by the reasonably optimizing of alloy element, hard, wear-resistant, corrosion resistant high-quality chromium is adopted in main component, and a small amount of high rigidity, good stability tungsten, improve the hardness of titanium alloy, wear resistance and erosion resistance, make it have good impact property, not easy to wearly to come off.
