SAE J2435

SCOPE

This specification covers electric resistance welded, flash controlled, normalized, single-wall SAE 1021 carbon steel pressure tubing. It is intended for use in pressure lines and in other applications requiring tubing of a quality suitable for bending, double flaring, beading and brazing. Material produced to this specification is not intended for single flare applications due to the potential leak path caused by the ID weld bead.

TESTING

Tubing produced to this specification will be submitted to the following test procedures according to SAE J1677; Flattening Test, Flaring Test, Reverse Flattening Test, Expansion Test, Hardness Test, Tensile Test, Pressure Proof Test, and a Nondestructive Electronic Test.

COMPARISON TO SAE J356

The grade of steel used to produce tubing to this specification differs from that of SAE J356 because it has higher carbon and manganese content. It is intended to service “high pressure” applications not recommended for SAE J356 tubing. Due to the chemistry, the forming characteristics will be somewhat diminished as compared to SAE J356.
