This SAE Standard covers sub-critically annealed or normalized electric resistance welded flash controlled single-wall high strength steel tubing intended for use in hydraulic 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 ID weld bead. Nominal reference working pressures for this tubing are listed in ISO 10763 for metric tubing and SAE J1065 for inch tubing.
This specification also covers SAE J2613 Type-A tubing. The mechanical properties and performance requirements of standard SAE J2613 and SAE J2613 Type-A are the same. The designated differences of Type-A tubing do not imply that Type-A tubing is in anyway inferior to standard SAE J2613. The Type-A disignation is meant to address the unique manufacturing differences between sub-critically annealed and normalized tubing.
Tube assembly configurations made to specific geometry and components requiring thermal attachment methods in association with the sub-critically annealed material, may require qualification testing in accordance with ISO 19879. The use of Type-A material avoids this systemic testing as thermal processes will not compromise the structural integrity of the Type-A tube material.
In an effort to standardize within a global marketplace and ensuring 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
Guide users to preferred system
Eliminate inventory duplications
This SAE standard has been revised as part of a Five-Year Review to reflect changes in available steels and newly developed processes used to produce this product. Document changes include revisions to the Scope, Applicable and Related Publications list, Section 8.8 Pressure Proof Test information and the addition of J2613 Type-A material. Verbiage has been updated throughout the standard to align the document with other recently revised tube standards.

* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
