ASTM A519 Seamless Mechanical Steel Tubing
ASTM A519 covers several grades of carbon and alloy steel seamless mechanical tubing,either hot-finished or cold-finished.
A213 Grade T17 Steel tubes and pipes, to be used to respond to high-efficiency industrial waste incineration boilers, have been demand to maintain both high quality & high performance. There has also emerged a need of various steel tubes and pipes such as economic steel tubes and specially-shaped steel tubes. We assure that our A213 Grade T17 boiler steel tubes and pipes will fulfill your expectations in every aspect.
