ASTM A519 - Seamless steel pipe
Detailed introduction:
Application: mechanical parts, precision pipes.
Steel types: carbon steel, alloy steel.
Standard content: ASTM A519 is mainly applicable to seamless steel pipes used in mechanical processing, and is widely used in the manufacturing fields of automotive parts, mechanical engineering, precision instruments, etc.
Main applications:
Automotive industry parts.
Mechanical, hydraulic, pneumatic systems.
Precision pipes and instrument pipes.
ASTM A519 is used for machining and hydraulic components, with common grades 1026 and 4130. Sizes range from OD 1/8 inch to 16 inches (≈406mm), and wall thickness is provided as Schedule 10S–160. The chemical composition of 1026 pipe is C 0.22–0.28%, Mn 0.60–0.90%, Si 0.10–0.35%, P≤0.040%, S≤0.050%; 4130 is alloy structural steel: C 0.28–0.33%, Cr 0.80–1.10%, Mo 0.15–0.25%, Mn 0.40–0.60%, Si 0.15–0.35%. Physical properties include density 7.85g/cm³, Young's modulus 210GPa, and thermal conductivity 45–50W/(m·K). After quenching + tempering, the tensile strength can reach 600–850MPa, the yield strength 450–700MPa, and the elongation 15–25%.
