ASTM A519 1045 Seamless Precision Steel Tube
GNEE sells more than 1,500 tons of seamless and welded steel tubes to various engineering industries every year. Our goal is to ensure that our customers have the highest expectations for the delivery and product quality of A519 1045 Seamless Tube.
A{{0}} precision steel tube is a carbon steel that is known for its strength and impact resistance. It has a carbon content of 0.43-0.50%, which contributes to its hardness and strength. ASTM A519 1045 grade precision tube includes hot-finished seamless tube and cold-finished tube. The outer diameter size of the tube is 10mm-323.8mm, and the outer diameter deviation has a certain range.
A519 1045 seamless carbon steel precision tube is widely used in mechanical structural parts, tool manufacturing and automobile manufacturing.
