ASTM A519 Seamless Pipe
ASTM A519 seamless pipe is a high-quality carbon steel and alloy steel mechanical pipe widely used in various machining and pressure applications.
The production process mainly includes hot rolling and cold drawing. The hot rolling process is suitable for large-size pipes and can provide good mechanical properties; the cold drawing process is suitable for small-size pipes and can provide high precision and smooth surface.
The following is a comparison of common material grades and their main components and mechanical properties:
Grade | C(%) | Mn(%) | Yield Strength | Tension strength | Elongation |
1010 | 0.08-0.13 | 0.30-0.60 | 205 | 350-450 | 15-25 |
1020 | 0.18-0.23 | 0.30-0.60 | 250 | 400-500 | 15-25 |
1045 | 0.43-0.50 | 0.60-0.90 | 310 | 570-700 | 10-20 |
4130 | 0.28-0.33 | 0.40-0.60 | 435 | 665-885 | 20-30 |
4140 | 0.38-0.43 | 0.75-1.00 | 415 | 655-850 | 15-25 |
ASTM A519 seamless pipe is widely used in transmission shafts and bearings in the automotive industry, pipelines and drilling equipment in oil and gas, hydraulic cylinders and gears in machinery manufacturing, brackets for engineering machinery, and steel structures in the construction industry.
