SAE J2614 Mechanical Steel Tubes are high strength electric resistance welded (ERW), cold drawn steel tubes with enhanced strength compared to low carbon electric resistance welded (ERW) steel tubes used in hydraulic pressure systems. These tubes are made from micro-alloyed steel with controlled alloying elements like niobium, vanadium or titanium to have a minimum tensile strength of 500 MPa with very good ductility for bending, flaring, cold forming, welding and brazing. They are used in critical hydraulic applications due to their exact dimensions and uniformity in their mechanical characteristics. They are designed to suit various pressure and engineering needs and form part of our carbon steel tubing range, complementing our SAE J525 Mechanical Steel Tubes and EN 10305-1 Seamless Precision Steel Tubes.
Amardeep Steel is an established manufacturer and supplier of Mechanical Steel Tubes as per the SAE J2614 specification in India which provides complete material traceability, various sizes and reliable global supply of the EN 10204 3.1 certified steel tubes.

Frequently Asked Questions
1. What is SAE J2614 Mechanical Steel Tubing?
SAE J2614 Mechanical Steel Tubing is a cold-drawn, electric resistance welded (ERW) steel tube designed for high-pressure hydraulic applications. It is manufactured to SAE J2614 standards for high strength and reliable performance.
2. What is the difference between SAE J2614 and SAE J525 tubing?
SAE J2614 tubing is manufactured from micro-alloyed steel and offers a minimum tensile strength of 500 MPa, making it suitable for higher-pressure hydraulic systems. SAE J525 tubing is made from low-carbon steel and is intended for general hydraulic and mechanical applications.
3. What material is used to manufacture SAE J2614 mechanical steel tubes?
SAE J2614 mechanical steel tubes are manufactured from micro-alloyed steel containing controlled additions of niobium, vanadium, or titanium to achieve higher strength.
4. What is the minimum tensile strength of SAE J2614 tubing?
SAE J2614 tubing has a minimum tensile strength of 500 MPa, providing excellent strength for demanding hydraulic applications.
5. Is SAE J2614 tubing suitable for high-pressure hydraulic applications?
Yes. SAE J2614 tubing is specifically designed for high-pressure hydraulic systems and offers excellent strength, durability, and pressure resistance.
6. Can SAE J2614 mechanical steel tubes be bent, flared, and welded?
Yes. SAE J2614 tubing supports bending, flaring, and cold forming. When brazing or welding is used as a tube end-joining method, the structural integrity of the tube material can potentially be compromised by application engineering before specifying a thermal joining method.
