Global Leader of
ASTM A519 GRADE1020 / AISI 1020 / SAE1020 SEAMLESS TUBING
ASTM A519 / A519M, ASME SA519 / SA519M SAE1020 is the standard applicable to seamless carbon and alloy steel mechanical tubing.
ASTM A519 GR. 1020 Hot Rolled Steel Tube has exceptionally simple and robust mechanism, self-cleaning and non-clogging mechanism, power saving, maintenance free, big solid handling capability, and as well has a quality for enduring reliable longer life and performance. ASTM A519 Boiler Tubes GR. 1020 as well has a number of outstanding features to provide like having Reliability, Flawless performance, Better efficiency and more. No matter what additional processing your Grade 1020 Hot Finished Seamless Tubing may need, we can handle it. We have stock a complete range of ASTM A519 Grade 1020 Carbon Steel Seamless Tubing in out diameter tube sizes 6mm-323.8mm and Nominal bore NB sizes 5NB-300NB.
ASTM A519 covers several grades of carbon and alloy steel seamless mechanical tubing.
ASTM A519 covers both seamless hot-finished mechanical tubing and seamless cold-finished mechanical tubing in sizes up to and including 12 3⁄4 in. (323.8 mm) outside diameter for round tubes with wall thicknesses as required.
