Abstract
The invention discloses an aluminium alloy seamless steel tube. The aluminium alloy seamless steel tube comprises the following ingredients in percentage by mass: 3.0-3.5% of Cr, 2.5-3.0% of Mn, 1.5-2.0% of Cu, 0.5-1.0% of W, 1.3-1.8% of Mo, 0.5-1.0% of Co, not greater than 0.1% of Si, not greater than 0.3% of Fe, and balance Al and inevitable trace elements. Through said manner, the strength, hardness, wear resistance, corrosion resistance and the like of the aluminium alloy seamless steel tube disclosed by the invention can be improved, and the dimensional stability and pressure resistance of the aluminium alloy seamless steel tube are ensured.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of aluminium alloy seamless steel pipe.
Background technology
Alloy seamless steel pipe for having hollow section, periphery do not have jointed rectangular steel.Steel pipe has hollow section, and a large amount of pipeline being used as conveyance fluid, as the pipeline etc. of transfer oil, Sweet natural gas, coal gas, water and some solid materials.Alloy seamless steel pipe is compared with the solid steel such as round steel, when bending resistance twisting strength is identical, lighter in weight is a kind of economic section steel products, now be widely used in manufacturing structure part and mechanical component, as the steel scaffolding etc. in petroleum transport, banister, bicycle frame and building operation.
The material of alloy seamless steel pipe generally selects chrome molybdenum, ensure its high temperature resistant, low temperature resistant, corrosion resistant performance, and traditional aluminium alloy is due to lighter weight, intensity, hardness etc. are all less than chrome molybdenum, carrying capacity performance is also more weak, the material of generally it goes without doing weldless steel tube.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, a kind of aluminium alloy seamless steel pipe is provided, the intensity of aluminium alloy seamless steel pipe, hardness, thermotolerance, erosion resistance etc. can be improved, and ensure dimensional stability and the carrying capacity performance of aluminium alloy seamless steel pipe.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of aluminium alloy seamless steel pipe, described aluminium alloy seamless steel pipe comprises the following ingredients formed by mass percentage: Cr:3.0%-3.5%, Mn:2.5%-3.0%, Cu:1.5%-2.0%, W:0.5%-1.0%, Mo:1.3%-1.8%, Co:0.5%-1.0%, Si :≤0.1%, Fe :≤0.3%, all the other are Al and inevitable trace element.
In a preferred embodiment of the present invention, described inevitable trace element is rare earth element.
In a preferred embodiment of the present invention, the mass percent of described inevitable trace element is 0.05%-0.3%.
The invention has the beneficial effects as follows: mated by the reasonably optimizing of alloy element, improve the intensity, hardness, thermotolerance, erosion resistance etc. of aluminium alloy seamless steel pipe, and ensure dimensional stability and the carrying capacity performance of aluminium alloy seamless steel pipe.
