ASTM A519 tube is a kind of carbon and alloy steel tube designed for mechanical purposes. Hot finished and cold finished are 2 delivery states. Seamless tube made in hot rolling way without welding process and shall be made into other shapes in the cold finish process. It is mainly used for rollers, heavily machined parts and sleeves.

OURWAY experienced experts can also offer custom fabrication like steel pipe and tube cutting, and will ship your product ASAP. No matter what extra change you may need with ASTM A519 mechanical tubing may need, OURWAY can do it for you.
