Product Description

SAE J524 Low Carbon Seamless Steel Tube Machining for Bending


Quick Detail:

Standard:  SAE J524 Seamless Steel Tubing                           
J524 Seamless Low Carbon Steel Tubing Annealed for Bending and Flaring          
Applications:  for Bending and Flaring to auto parts         

Size range: O.D.:6-88.9mm     W.T.:1-15mm      L: According to customer Order     
The tubing is cold drawn size and after forming shall be annealed in such a manner as  to produce finished product which meet the SAE J524 requirement and customer's requirement.

Lengths of finished tubing is reasonably stragiht and have smooth ends free from burrs.

Tubing is free from scale and injurious defects and have a workmanlike finish.

Surface imperfections such as handling marks, die marks, or shallow pits shall not be considered injurious

defects provided the imperfections are within the tolerance specified for diameter and wall thickness.

The removal of such surface imperfections is not required.



The finished tubing satisfactorily meet the following performance tests in SAE J1677

  • Flattening test
  • Flaring test
  • Reverse Flattening test
  • Expansion Test
  • Hardness Test
  • Tensile Test 
  • Elongation Test
  • Pressure Proof Test
