SAE J2467:2020 pdf free.Welded and Cold-Drawn, SAE 1021 Carbon Steel Tubing Normalized for Bending, Single Flaring, Cold Forming, Welding, and Brazing
The tubing shall be made from a single strip of flat rolled steel shaped into a tubular form, the edges of which are joined and fused together by electric resistance welding. After forming and welding, the tubing shall be normalized and subjected to a cold drawing operation that shall result in a wall thickness reduction of 8% minimum. Subsequent to cold drawing, the tubing shall be normalized via an atmospherically controlled method to produce a finished product that will meet all requirements of this document.
The tolerances applicable to the tubing ouside diameter (OD) and inside diameter (ID) are shown in Table 1. The tolerances applicable to tubing wall thickness are shown in Table 2. Dimensional tolerances can only apply to two of the three tubing dimensions (OD, ID, or wall). Unless otherwise agreed upon between the purchaser and producer, dimensional tolerances shall apply to the tube OD and wall dimension.
The outside and inside surface condition of the tube are critical in order to prevent possible leak paths on flared connections,mechanical form connections, hose bead connections, or other applications where the surface of the tube becomes the sealing surface. The surface of the tube shall be free of excessive roll marks, score marks, chatter marks, or other surface imperfections that are considered detrimental to the function of the tubing. Depth of roll marks, score marks, chatter marks,or other surface imperfections shall not reduce wall thickness below the tolerances listed in Table 2.
The tubing is to be heated to a temperature above the upper transformation point using an atmospherically controlled furnace, and then cooled in a protective atmosphere to produce a finished product that shall meet the requirements of this document.
Tubing shall be made from low-carbon, flat rolled steel conforming to the chemical composition in Table 3. The steel shall be made by the basic oxygen 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 conform to the requirements specified. If a product analysis is required,the tolerances shall be as specified in SAE J409, Table 3.SAE J2467 pdf free download.
