5、r Bending, Double Flaring, and Bending RATIONALEThis SAE standard has been revised as part of the SAE five year review process and to bring this document into line with global standardization.1. SCOPE This SAE Standard covers sub-critically annealed electric resistance welded flash controlled single

6、-wall high strength low alloy steel tubing intended for use in hydraulic pressure lines and in other applications requiring tubing of a quality suitablefor bending, double flaring, cold forming, welding and brazing. Material produced to this specification is not intended to be used for single flare

7、applications due to the potential leak path that would be caused by the ID weld bead. The grade of material produced to this specification is of micro-alloy content and is considerably stronger and intended to service higher pressure applications than like sizes of the grades of material specified i

8、n SAE J356 and SAE J2435. Due to the alloy content of the material, the forming characteristics of the finished tube are equal to or better, when compared to SAE J356 and SAE J2435. Nominal reference working pressures for this tubing are listed in ISO 10763 for metric tubing and SAE J1065 for inch t

9、ubing. CAUTION: When brazing or welding is used as a tube end joining method, the structural integrity of the tube material can potentially be compromised due to the degradation of the areas affected by the thermal effect applied to the tubing; therefore, the ISO 10763 and SAE J1065 nominal referenc

10、e working pressures may not be applicable. Brazed and/or welded tube assembly configurations made to specific geometry and components bill of material in association with this material, may require qualification testing in accordance with ISO 19879 Test Methods for Hydraulic Fluid Power Connections.

11、 Cold forming the tube end configurations avoids this systemic testing by not compromising the tube material structural integrity. 2.

MANUFACTURE The tubing shall be made from a single strip of s

28、teel shaped into a tubular shape, the edges of which are joined and fused by electric resistance welding. After forming and welding, the outside flash shall be removed to provide a smooth surface. The inside flash shall be of uniform contour, free from saw-tooth peaks and controlled in height by sea

29、m-welding techniques or by cutting, not by hammering or rolling. The inside flash height shall conform to the following as in Table 1. The tubing shall be sub-critically annealed via a controlled method to produce a finished product, which will meet all requirements of this document. Sub-critically

30、anneal - An annealing treatment in which steel is heated to below the A1 temperature, then slowly cooled to room temperature. A1 temperature is the critical transformation temperature depending on steel classification. TABLE 1 - INSIDE FLASH HEIGHT Nominal Wall ThicknessmmMaximum Flash Height(1)(2)T

For tubes having an ID greater than 8 mm, the height of the inside weld flash shall be measure with a ball micrometer having a 3.96 mm 0.41 mm radius from th

32、e anvil or ballpoint. For tubes having an ID 8 mm or less, screw thread micrometers shall be used. The height of the flash shall be the difference between the thickness of the tube wall at the point of maximum height of the flash and the average of the wall thickness measured at points adjacent to b

33、oth sides of the flash. 2. Tubing with an ID that is smaller than the producers capability to scarf the ID weld bead, shall be produced as “flash in“ tubing. Seam welding techniques may be applied to control the ID flash height. The maximum ID flash height, however, will be determined by agreement b

34、etween the producer and the purchaser.4. DIMENSIONS AND TOLERANCES The tolerances applicable to tubing outside diameter are shown in Table 2. The tolerances applicable to tubing wall thickness are shown in Table 3. For specific common ODs and wall sizes, see ISO 10763 for metric tubing and SAE J1065

35、 for inch tubing. Particular attention shall be given to areas adjacent to the weld to insure against thin spots and/or sharp indentations.

40、 tolerances include allowance for crown on flat-rolled steel.5. MANUFACTURING STANDARDS 5.1 Straightness Tubing shall be straightened to a tolerance of 0.8 mm in 1000 mm. Straightness tolerances shall be measured by placing a 1000 mm straight edge against the tube while lying on its neutral axis. Th

41、e point of maximum deflection of the tube from the straight edge should not be more than allowed by the specification when measured with a feeler gauge. 5.2 Tubing End Condition The tubing will be produced using normal mill cut off practices. This shall include, but not limited to, punch-cut ends, d

42、ouble-cut ends and rotary-cut ends. Care shall be taken to minimize the distortion of the tube ends. Distortion of the tube must not affect the normal re-cutting processes that will be performed by the end user. Ends that require further processing will be addressed by agreement between the producer

43、 and the tube purchaser. 5.3 Finish The outside surface finish of the tube is critical to prevent possible leak paths on double flare connections, mechanical formed connections or applications where the outside surface of the tube becomes the sealing surface of the finished connection. The outside s

44、urface finish of the tube shall be free of excessive roll marks, score marks, chatter marks or other surface imperfections that may be considered detrimental to the function of the finished tube. 5.4 Thermal Treatment The tubing is to be sub-critically annealed by heating to a temperature below the

45、transformation point and then slowly cooled to room temperature. Special attention to the mechanical properties, especially the Rockwell B85 Hardness Target, should be made to produce tubing suitable for bending and forming for hydraulic pressure applications. However, to obtain acceptable hardness

46、characteristics, the yield strength and the tensile strength shall not be compromised and 30% minimum elongation shall be maintained.6. MATERIAL The tubing shall be made from alloy steel strip conforming to the chemical composition in Table 4. The steel shall be made by the open-hearth basic oxygen

47、or electric furnace process. A ladle analysis of each heat shall be made to determine the percentages of the elements specified. The chemical composition thus determined shall be reported to the purchaser or purchasers representative, if requested, and shall be conform to the requirements specified.

48、 If a check analysis is required, the tolerances shall be as specified in SAE J409, Table 3.
