Application Of Seamless Mechanical Tubes
Seamless mechanical tubes are tubes with enhanced precision and dimensional accuracy. These tubes are often used in applications where tight tolerances, smooth surfaces, and high strength are critical. It can be used in automotive components, aerospace industry, oil and gas exploration, high-pressure hydraulic systems, precision machinery, power generation, medical devices, industrial machinery.
Standard And Grades Of Mechanical Tubes
Characteristic Of ASTM A519 Mechanical Tubes
ASTM A519 is a specification that covers several grades of carbon and alloy steel seamless mechanical tubing. This standard outlines the requirements for these tubes, which are intended for use in mechanical and structural applications. Seamless mechanical tubes produced to the ASTM A519 specification are known for their high strength, durability, and precision.
ASTM A519 covers a range of grades, including but not limited to 1010, 1020, 1026, 4130, 4140, 4142, 4145, 4340, and others. Each grade has specific chemical composition and mechanical property requirements.
