SAE J525 Hydraulic Carbon Steel Tubes Supplier in India
For hydraulic lines and other applications requiring flexible and bendable tubing, we also produce cold drawn and annealed seamless low carbon steel pressure tubing. Hoses that meet SAE J525 specifications are available in 20-foot lengths. The material is made from.
A weld mill was used to roll flat sheets of raw material. During hydraulic fluid line applications, this material is dead soft when produced, making it easy to bend and flare. There are AISI classes 1008 and 1010, as well as 1020 and 1026. The tube is suitable for cold working after a normalizing heat treatment.
For pressure lines and other applications requiring flexibility, forming, and brazing capabilities, this standard specifies normalised electric-resistance welded, cold-drawn, single-wall, low-carbon steel pressure tubing.
SAE J525 Steel Tube is suitable for hydraulic applications and other applications requiring tubing with a quality suitable for flaring and bending. The ODs and IDs of our tubes are exceptionally clean and bright, and they are shipped with capped ends to prevent contamination.
Our company manufactures, supplies, exports, and distributes low carbon steel pipes and tubing. We supply and stock welded tubing based on SAE J525 Steel Tube for hydraulic parts. When tubes are specified by their diameters (or their inner diameters) and their nominal wall thicknesses, they must have tolerances that correspond with the diameter and no thickness variation exceeding 10%.
We also provide and stock Corten steel tubing that is highly resistant to atmospheric corrosion, making it ideal for outdoor applications.
J525 Hydraulic Welded and Seamless Tubing Quality
After normalizing the tubing, cold working must be performed. In cold working, the walls must be reduced by at least 8 percent, resulting in a minimum reduction of 15 percent. An annealed product that meets all specifications will be produced by cold-working the tubing.
This hydraulic tube is made of welded low-carbon steel tubing that has been annealed for bending and flaring. High-quality tubing for bending, flaring, forming, and brazing. The hydraulic components are used in heavy equipment, agriculture, off-road vehicles, automotive, steering and transmission components, process and utility applications, and other hydraulic applications.
In addition, after final sizing, our J525 high-pressure tubing undergoes several cold-drawn reductions, intermediate anneals, and a dead-soft anneal. Thus, the tubing is consistently of high quality and is easy to bend and flare.
With similar chemical and mechanical properties, both J524 and J525 are used in hydraulic applications. J525 is welded from flat stock, on the other hand. Flaring is usually best achieved with J524 Seamless. However, both products are of high quality and have similar specifications.

Flattening Test
A section at least three inches in length shall be taken from every 1500 feet or less of finished tubing and shall be flattened between parallel plates to three times the wall thickness of the tube. The weld shall be placed at a point of 90 degrees from the direction of applied force. Any cracking or flaws revealed by this test shall be cause for rejection.

FAQs for J525 Hydraulic Tubing
J524 and J525 hydraulic tubing are both used in hydraulic systems, but they differ in their manufacturing process and material properties. J524 tubing is seamless, offering a smooth, continuous finish, while J525 tubing is typically welded. J525 is designed for use in low to medium-pressure hydraulic systems, whereas J524 is more commonly used for higher-pressure applications due to its seamless construction.
- J525 Hydraulic Tube (SAE J525 Tube)
- J525 Welded Hydraulic Tubing (SAE J525 Hydraulic Tubing)
- J525 Tubing (SAE J525 Steel Tubing)
- SAE J525 DOM Tubing (SAE J525 Hydraulic Tube)
- C1010 Hydraulic Line Tubing (AISI C1010 DOM Tube)
- C1010 Steel DOM Welded Tube (SAE J525 Steel Welded Hydraulic Tubing)
- C1010 J525 Hydraulic Tubing (C1010 SAE J525 Welded and Cold-drawn Steel)
These different types of J525 tubing are tailored for various applications, with options including welded and cold-drawn steel tubing for hydraulic lines, offering strength and durability.
J525 hydraulic tubing is generally welded, making it distinct from seamless tubing like J524. The welded construction of J525 allows for easier production at lower costs while maintaining high strength and reliability. This type of tubing is ideal for medium-pressure hydraulic systems and is often used in applications where seamless tubing is not necessary. The welded seam does not affect the overall performance of the tubing in most applications.
