SAE J525
SAE J525 tubing is manufactured from high-quality mild carbon steel, processed by electric resistance welding and then fully normalized to achieve uniform grain structure and excellent ductility. It is specifically designed as a hydraulic tube with thick walls to handle pressure applications while ensuring precision and safety.
Standard: SAE J525
Manufacturing Process: Electric Resistance Welded (ERW), Normalized
Wall Thickness: Thick wall, per SAE J525 requirements
Shape: Round tube
Finish: Smooth, suitable for bending and flaring
