ASTM A519 Grade 4140/4130 Carbon Steel Seamless Mechanical Steel Pipe
Hebei shengtian pipe-fitting group Co., ltd. stocks a huge selection of A519 seamless mechanical steel tube, with sizes and styles to match any requirements. The ASTM A519 steel tube specification covers both hot-finished and cold-finished mechanical tubing in sizes up to 12-3/4” O.D. A519 is available in round, square, and rectangular profiles, and in special sections.
A519 seamless tubing is commonly used in applications requiring machining, heat treating, close tolerances, smooth finishes, and/or definite physical properties.
ASTM A519 Steel Tube Materials & Manufacturing
Steel used to produce A519 steel tube may be made by any process. If you require a specified type of melting, please note this in your Request for Quote or when ordering. A519 tubes must be made in a seamless process and either hot finished or cold finished, as specified.
