ASTM A519 Seamless Mechanical Steel Tube

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…
