This SAE Standard covers normalized electric resistance welded flash controlled single-wall, SAE 1021 carbon steel pressure tubing intended for use as pressure lines and in other applications requiring tubing of a quality suitable for bending, double flaring, cold forming, welding, and brazing. Material produced to this specification is not intended to be used for single flare applications due to the potential leak path caused by the inside diameter (ID) weld bead or scarfed region. Assumption of risks when using this material for single flare applications shall be defined by agreement between the producer and purchaser. The grade of material produced to this specification is higher in carbon and manganese content than the grade of material specified in SAE J356 and is intended to service higher pressure applications than equivalent sizes of SAE J356. Due to the higher carbon and manganese content, the forming characteristics of the finished tube are diminished versus the SAE J356 product. Special attention to the overall forming requirements of the finished assembly shall be taken into consideration when specifying material produced to this specification. Refer to SAE J2551-1 for additional design and fabrication guidance associated with this material. Nominal working pressures for this material are listed in ISO 10763 and SAE J1065. When required, qualitication testing shall be in accordance with ISO 19879. In an effort to standardize within a global marketplace and ensure that companies can remain competitive in an international market, it is the intent to convert to metric tube sizes which will: Lead to one global system.
