ASTM A519 Cold Drawn Seamless Mechanical Steel Tube

ASTM A519 cold-drawn seamless mechanical steel pipe is a high-quality seamless steel pipe with precise dimensions and excellent performance.In terms of chemical composition, it covers a variety of carbon steel and alloy steel materials, such as 1008 steel with a carbon content of ≤0.10%, a manganese content of 0.30%-0.50%, and phosphorus and sulfur contents of ≤0.040% and 0.050% respectively; 4140 steel with a carbon content of 0.38%-0.43%, a manganese content of 0.75%-1.00%, and alloy elements such as chromium and molybdenum. Its manufacturing process adopts cold drawing. After cold drawing, the steel pipe has high dimensional accuracy and good surface finish, which can greatly save machining time.In terms of mechanical properties, the yield strength, tensile strength and elongation of different steel grades are different. For example, the cold-drawn yield strength of 1020 steel is ≥414MPa, the tensile strength is ≥483MPa, and the elongation is ≥5%.The steel pipe is w…
