SAE J524 seamless

As an industry leader in the production of seamless carbon and alloy steel pipes, SA179tubes.com supplies high quality cold drawn seamless and hot finished seamless pipe. In the cold draw process, dimensional accuracy, microstructure uniformity, and superior surface finish are closely controlled, making the tubing an excellent choice for applications requiring high pressure, high temperature, and extreme stress. Our chrome-moly products are excellent for applications that require a high strength-to-weight ratio.

Along with round, square, rectangular, and hexagon shapes, we offer a wide range of specialty profiles, such as cloverleaves, streamlines, and lemons, which can be configured to suit your individual needs. We are able to meet the exact requirements of our customers by sourcing both standard and specialty grades of materials through our vast network of mill suppliers. We can cut-to-length tubes with an outside diameter of 0.250″ to 11.000″ and a wall thickness that varies from 0.028″ to 1.187″. A long list of international standards can be met with tubes, including ASTM, SAE, EN, DIN, and JIS.

Cold drawn tubing offers superior machinability, better tolerances, and greater strength compared to hot finished products, making it an excellent choice for many demanding applications. Our exceptional capabilities can be found in the table below. Feel free to contact us if you have questions.

Its flaring and bending properties make J524 Seamless Hydraulic Tubing especially suitable for flaring and bending. Seamless Low Carbon Steel tubing that is Cold Drawn and Annealed for use in hydraulic lines. As a result, some industrial uses include Aircraft, Locomotive, Heavy Equipment, Automotive, and Agricultural applications. Therefore, J525 is a perfect choice where fittings, couplings, and fluid lines are used. As a further measure of cleanliness and prevention of contamination, all of our tubes ship with sealed endsSA179

Specifications

  • SAE J524 Seamless
  • AMS5050K
  • AISI 1008/1010
  • ASTM/ASME A/SA179 except for average wall, aluminum killed steel
  • EN10204 3.1.B
  • PED certified
  • OD x ID
  • Uniform Lengths
  • Dual Certified

A particular feature of our SAE J524 seamless is that it is available both as ERW (Electric Resistance Welded). All our tubing is manufactured to ensure a clean ID, a requirement for most hydraulic applications. Notably, our seamless hydraulic fluid line metallurgical composition is cold drawn 1010 steel which meets AMS 5050-G, JIC specs, ASTM A-179, and SAE J524 seamless.

Characteristics

  • Uniform ductile tubing ideal for easy flaring and bending
  • Smooth clean inside surface helps prevent damage to valves and cylinders
  • Hydraulic applications like diesel fuel injection, lubrication, generator pump, coil, air conditioner, and similar high-pressure applications
  • Unlike 4130 Seamless Alloy Steel Tubing, SAE J524 seamless is easily bent and flared
  • All material is dead soft annealed and drawn
  • Typical applications such as fittings, couplings, and fluid lines

As a result of multiple cold-drawn reductions, annealing both intermediate and after final tubing sizing, our SAE J524 seamless tubing has a high quality finish both inside and out. However, when handling tubing special care should be given not to drag, scratch or accidentally gouge since those imperfections may compromise tubing and cause leaks.

Has uniform ductility and a smooth clean inside surface

Seamless hydraulic tubing is produced as a seamless tube by rolling and piercing bar stock.  It then gets multiple cold-drawing reductions before a final cold draw guarantees tight dimensional tolerances and excellent surface finish.  After final sizing of the tube through cold drawing it undergoes intermediate annealing and a dead-soft annealing process to meet SAE J524 seamless requirements.
