SAE J524 TUBING
Seamless low carbon steel tubing to SAE J524, annealed in a controlled atmosphere. The annealed condition gives the ductility needed for tight bend radii and double flaring without cracking, which is why it is used for brake, fuel and instrument lines. Supplied in coils or straight lengths.
Price: quoted per specification. Steel prices move with the raw material market, so every quotation is confirmed at the time of order.
