ASTM A519 Grade 1045 Carbon Steel Seamless Tubings are Medium Carbon Steel Tubings with 0.43-0.50 % carbon content with combination of 0.60-0.90 % manganese.
ASTM A519 Grade 1045 Tubings are ductile and strong Tubings with long wearing properties. These Tubings are manufactured as per ASTM Specification and commercially referred as carbon steel Tubings.

Hot rolled ASTM A519 1045 pipe, as the name implies, the temperature of rolled piece is high, so the deformation resistance is small, can achieve a large amount of deformation. Take the rolling of steel plate as an example, the thickness of continuous casting billet is about 230mm, and after rough rolling and finishing rolling, the final thickness is 1~20mm. At the same time, due to the small width to thickness ratio of steel plate, the size accuracy requirements are relatively low, it is not easy to appear plate shape problems, mainly to control the convexity. For the requirements of the organization, generally through the control of rolling cooling to achieve, namely control of the finishing rolling temperature, the opening temperature.
ASTM A519 1045 pipe hot rolling process:
Round tube billet → heating → perforating → head → annealing → pickling → oiling (copper plating) → multipass cold drawing (cold rolling) → billet tube → heat treatment → straightening → hydrostatic test (flaw detection) → marking → warehousing.
