This SAE Standard covers normalized electric-resistance welded flash-controlled single-wall, low-carbon steel pressure tubing intended for use as pressure lines and in other applications requiring tubing of a quality suitable for bending, double flaring, beading, forming, 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. This specification also covers SAE J356 Type-A tubing. The mechanical properties and performance requirements of SAE J356 and SAE J356 Type-A are the same. The SAE J356 or SAE J356 Type-A designation define unique manufacturing differences between coiled and straight material.

This SAE Standard covers stress relieved electric resistance welded flash controlled single wall high strength low alloy steel tubing intended for use in high-pressure hydraulic lines and in other applications requiring tubing of a quality suitable for bending, double flaring,cold forming 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. The grade of material produced to this specification is of micro-alloy content. Nominal reference working pressures for this tubing are listed in ISO 10763 and SAE J1065. Brazed and/or welded tube assembly configurations made to specific geometry and components in association with this material may require qualification testing in accordance with ISO 19879. Cold forming the tube end configurations avoids this systemic testing by not compromising the structural integrity of the tube material.

This Information Report describes eddy current testing, flux leakage testing, ultrasonic testing, and magnetic particle testing of steel tubing. The purpose of these testing methods is to expose flaws in the tube material or weld zone, such as discontinuities, seams, cracks, holes, voids, and other imperfections characteristic to the specific construction of the tubing. When agreed upon between the producer and purchaser, nondestructive testing is used in lieu of destructive hydrostatic pressure proof testing. Aircraft and Aerospace applications were not considered during the preparation of this document.

This specification covers stress relieved 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, and brazing. The grade of material produced to this specification is of micro-alloy content. Nominal reference working pressures for this tubing are listed in ISO 10763 and SAE J1065. CAUTION: Sub-critically annealed steels are often produced using anneal temperatures below the Lower Critical Temperature (AC1) of the given steel to achieve the desired strength levels. Welding, brazing, or other processing methods that subject the tube material or assembly to temperatures near or above AC1 might initiate isothermal transformation of the tube microstructure and compromise the strength of the tube in the heat affected zone by further annealing the tube.
