This specification covers sub-critically annealed electric resistance welded and cold-drawn single-wall high strength low alloy 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. The grade of material produced to this specification is of micro-alloy content and is considerably stronger and intended to service higher pressure applications than like sizes of the grades of material specified in SAE J 525 and SAE J 2467. Due to the alloy content of the material, the forming characteristics of the finished tube are equal to or better, when compared to SAE J 525 and SAE J 2467. Nominal reference working pressures for this tubing are listed in SAE J 1065.
