This SAE Standard covers cold drawn and annealed seamless low-carbon steel pressure tubing intended for use as hydraulic lines and in other applications requiring tubing of a quality suitable for flaring and bending.
This five year review of this standard resulted in changes identified by the bar on the left side of the page and are described as follows: a. Added SAE and other international standards to the "Related Publications" section because these documents are related to J524 tubing. b. In Section 8. Performance Requirements, removed un-needed J1677 paragraph numbering to eliminate unnecessary confusion. c. In Section 8. Performance Requirements, added reverse flattening, hardness, tensile and elongation test.
