ASTM A519 Seamless Mechanical Steel Tube

ASTM A519 seamless mechanical steel pipe is an important basic material widely used in the field of mechanical manufacturing, and plays a key role with its excellent characteristics.Its chemical composition is strictly controlled, covering a variety of materials such as low carbon steel, other carbon steel and alloy steel. For example, the carbon content of 1010 steel is 0.08%-0.13%, the manganese content is 0.30%-0.60%, and the maximum phosphorus and sulfur content are 0.050% and 0.040% respectively; the carbon content of 4140 steel is 0.38%-0.43%, the manganese content is 0.75%-1.00%, and it also contains alloy elements such as chromium and molybdenum. In terms of material composition, it uses specific high-quality steel, and undergoes a strict composition blending and refining process to ensure that the material has good comprehensive performance.Its strength and toughness have achieved a delicate balance. It can not only withstand large mechanical external forces, such as in the tr…
