Abstract
The utility model discloses an austenitic stainless steel special section tube for an engine, which is characterized in that the austenitic stainless steel special section tube is a square welded tube with the external side length of 12mm X 12mm to 20mm X 20mm, the wall thickness of 0.5mm to 1.5mm and the length of L. Four corners are filleted corners with reverse R 2mm +/-0.5mm, the dimension error of the external sides is controlled within tolerance limit of +/-0.05mm to +/-0.01mm, the flatness of four faces is 0.01mm, the straightness is 0.1mm/300mm, the angles of the four corners are controlled in a range of 90 degrees +/-0.2 degree, and the protrusion of a welded joint is larger than 0 and smaller than 0.08mm. The austenitic stainless steel special section tube for the engine has no tendency of intergranular corrosion by means of E detection according to a GB/T4334-2008 method. The austenitic stainless steel special section tube for the engine can meet requirements in aspects of tightness, strength and overall dimension.
Description
Technical field
The utility model relates to a kind of special-shaped Stainless Steel Tube, and particularly motor is used the Austenitic Stainless Steel steel tubing in different shapes.
Background technique
Motor car engine is an energy transfer mechanism, and the heat energy with gasoline (diesel oil) or rock gas changes mechanical energy into.And realize that this function needs complicated transmission system, steel tubing in different shapes mainly is responsible for fuel delivery and is responsible for use as toxic emission recirculation.Existing motor steel tubing in different shapes all is difficult to the requirement that reaches from sealing, intensity and the boundary dimension of weld seam.
The model utility content
The utility model technical problem to be solved is that the motor that provides a kind of sealing, intensity and boundary dimension of weld seam all can meet the demands to the existing deficiency of available engine steel tubing in different shapes uses the Austenitic Stainless Steel steel tubing in different shapes.
The utility model technical problem to be solved can realize through following technological scheme:
Motor is used the Austenitic Stainless Steel steel tubing in different shapes, it is characterized in that, is outer length of side 12mm * 12mm～20mm * 20mm; Wall thickness is 0.5mm～1.5mm, and length is the square welded pipe of L, and wherein four jiaos are fallen the fillet of R2mm ± 0.5mm; Outer length of side size error is controlled at ± 0.05mm～± the 0.1mm tolerance range in; The planeness at four sides is 0.1mm, and straightness accuracy is 0.1mm/300mm, and four jiaos angle is controlled at 90 ° ± 0.2 °; Weld flush is greater than 0, and less than 0.08mm.
Through detecting, to press GB/T4334-2008 method E and detect, the utility model does not have the intergranular corrosion tendency.
The requirement no matter motor of the utility model can both reach from sealing, intensity and the boundary dimension of weld seam with the Austenitic Stainless Steel steel tubing in different shapes.
