SAE J525 Thick Wall Mild Steel Tube – Alloy Hydraulic Tube for Precision Instruments

Material

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.

Specifications

  • 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
