This specification covers sub-critically annealed or normalized electric resistance welded and cold-drawn 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, flaring, cold forming, welding and brazing. Nominal reference working pressures for this tubing are listed in ISO 10763 for metric tubing and SAE J1065 for inch tubing.
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 SAE J2614 Type-A material. Verbiage has been updated throughout the standard to align the document with other recently revised tube standards.
