Welded Low-Carbon Steel Tubing Suitable for Bending, Flaring, Beading, Forming and Brazing
The SAE J526 Standard covers electric-resistance welded single-wall low-carbon steel pressure tubing intended for general automotive, refrigeration, hydraulic, and other similar applications requiring tubing of a quality suitable for bending, 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 that would be caused by the ID weld bead. The material produced to this specification is intended to service pressure applications where severe forming and bending is not required. As this material may exhibit mechanical properties that reduce some desired forming characteristics versus SAE J356, the severity of the forming requirements of the finished assembly should be considered when utilizing material produced to this specification.
The five-year review of this standard brings this document up to date in relation to similar SAE tube specifications and enhances the users awareness of the need to work closely with the tube producer to correlate end use requirements with this material specification.
