The updates include the following: Rev

6、ised documents listing, Verbiage changes to improve the technical meanings of specific terms and expressions Clarified wall thickness reduction requirement in section 3.0 Revised wording of section 5.2 Recommendation for the use of metric size materials. Revision of chemical requirements to harmoniz

7、e with SAE J403 Added notation to clarify test agreement noted on 8.8 Pressure Proof Test Added notation to clarify test note on 8.9 Nondestructive Electronic Test 1. SCOPE The SAE Standard covers normalized electric resistance welded, cold-drawn, single-wall, SAE 1021 carbon steel pressure tubing i

8、ntended for use as pressure lines and in other applications requiring tubing of a quality suitable for bending, flaring, forming, and brazing. The grade of material produced to this specification is higher in carbon content and manganese content than the grade of material specified in SAE J525 and i

9、s intended to service higher pressure applications than equivalent sizes of SAE J525. Due to the higher carbon and manganese content the forming characteristics of the finished tube are diminished versus the SAE J525 product. Special attention to the overall forming requirements of the finished asse

10、mbly shall be taken into consideration when specifying material produced to this specification.

MANUFACTURING STANDARDS 5.1 Straightness Tubing shall be straightened to a tolerance of 1 mm over a 1000 mm length. 5.2 Tubing End Condition The tubing shall be produced usi

31、ng normal mill cut-off practices, e.g., punch-cut ends, double cut ends or rotary-cut ends. Tube end distortion must be minimized; end condition shall not affect normal re-cut processes performed by the end user. Extraordinary end cut processing requirements shall be defined by agreement between the

32、 producer and purchaser. 5.3 Surface Finish The outside and inside surface condition of the tube are critical in order to prevent possible leak paths on flared fittings, mechanical form fittings, or other applications where the surface of the tube becomes the sealing surface. The surface of the tube

33、 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. 5.4 Thermal Treatment The tubing is to be heated to a temperature above the upper transformation point using an atmospherically controlled

34、 method, and then cooled in a protective atmosphere. 6. MATERIAL 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 determin

35、e the percentages of the elements specified. The chemical composition thus determined shall be reported to the purchaser, or his representative, if requested, and shall conform to the requirements specified. If a check analysis is required, the tolerances shall be as specified in SAE J409, Table 3.

TEST CERTIFICATES A certificate of compliance to the performance requirements shall be furnished to the purchaser by the

41、producer, if requested in the purchase agreement. The tube producer shall be able to certify that each heat lot used to produce the tubing complies with the performance requirement. 10. CLEANLINESS The inside and outside surfaces of the finished tubing shall be commercially bright, clean, and free f
