SAE J524 Seamless Low-Carbon Steel Tubing Annealed for Bending and Flaring
This SAE Standard covers cold drawn and annealed seamless low-carbon steel pressure tu bingintended for use ashydraulic lines and in other applications requiring tubing of a quality suitable for flaring and bending.
The tubing shall be cold drawn to size and after forming shall be annealed in such a manner as to produce a finishedproduct which will meet all requirements of this document.
The tolerances applicable to tubing outside diameter are shown in Table 1. The wall thickness shall not vary more than+1O% for tubing having 12.7 mm or larger, nominal inside diameter nor more than I15% for tubing having a smallernominal inside diameter. T ubing outside diameter and wall thickness shall be as specified by purchaser.
Lengths of finished tubing shall be reasonably straight and have smooth ends free from burrs. Tubing shall be free fromscale and injurious defects and have a workmanlike finish. Surface imperfections such as handling marks, die marks, orshallow pits shall not be considered injurious defects provided the imperfections are within the tolerances specified fordiameter and wall thickness. The removal of such surface imperfections is not required.
Outside diameter and wall thickness allow deviation mm
