Abstract
The invention discloses a high-hardness titanium alloy seamless steel pipe. The high-hardness titanium alloy seamless steel pipe is composed of main components and secondary components. The main components comprise, by mass, 38.5%-40.0% of Ti, 28.0%-30.5% of Cr, 17.5%-19.0% of Fe, 5.0%-7.0% of Al and 3.5%-5.0% of Mn. The content of the secondary components is 3.5%-5.0%, and the secondary components comprise three or more of C, B, Si, Zr, Mo and N. By means of the mode, the hardness of the titanium alloy seamless steel pipe can be improved, so that the high-hardness titanium alloy seamless steel pipe has good abrasion resistance, corrosion resistance and high temperature resistance.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of high-hardness titanium alloy weldless steel tube.
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 make surface hardening, obtains higher hardness and surface abrasion resistance, but the surface wear-resistant layer that this mode obtains 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-hardness titanium alloy weldless steel tube, can improve the hardness of titanium alloy weldless steel tube, makes it have good wear-resisting, corrosion-resistant, resistance to elevated temperatures.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of high-hardness titanium alloy weldless steel tube, described high-hardness titanium alloy weldless steel tube is made up of main component and submember, described main component comprises the following ingredients formed by mass percentage: Ti:38.5%-40.0%, Cr:28.0%-30.5%, Fe:17.5%-19.0%, Al:5.0%-7.0%, Mn:3.5%-5.0%, the content of described submember is 3.5%-5.0%, and it comprises more than three kinds in C, B, Si, Zr, Mo, N.
In a preferred embodiment of the present invention, described high-hardness titanium alloy weldless steel tube comprises the following ingredients formed by mass percentage: Ti:38.7%, Cr:29.5%, Fe:18.2%, Al:6.3%, Mn:4.1%, C:0.32%, B:0.25%, Si:0.03%, Zr:2.6%.
