ASTM A519 1010 seamless tube is the low carbon steel among the various grades of A519 mechanical tubing, providing superior machinability compared to all other A519 carbon steels. When purchasing high-grade ASTM A519 seamless mechanical tubing for manufacturing machined parts, bushings, liners, and automotive parts, Grade 1010 is the preferred choice as it provides easy machining due to its softer nature and free machining characteristics. USA Piping Solution, known for its premium quality mechanical tubing, provides ASTM A519 Grade 1010 seamless tubes in cold drawn seamless (CDS) form with certification.
ASTM A519 1010 Specification
All ASTM A519 Grade 1010 seamless tubes supplied by USA Piping Solution conform to the current revision of ASTM A519 and are produced by seamless rolling or extrusion followed by cold drawing to achieve precise dimensional tolerances. The Cold Drawn Seamless Mechanical Tubing process is the preferred supply form for Grade 1010 as it maximizes surface quality and dimensional control for machining applications.

ASTM A519 Grade 1010 Wall Thickness Tolerance Table
ASTM A519 specifies wall thickness tolerances based on the ratio of outside diameter to wall thickness (D/t ratio). The table below summarizes standard tolerances applicable to Grade 1010 CDS tubes. Tight-tolerance material is available upon request for precision machined components.
| Outside Diameter (OD) | Wall Thickness Tolerance (Over) | Wall Thickness Tolerance (Under) |
|---|---|---|
| OD up to 1.500 in (38.1 mm) | +15% | -15% |
| OD 1.501 in to 4.000 in (38.1 to 101.6 mm) | +12.5% | -12.5% |
| OD over 4.000 in (101.6 mm) | +10% | -10% |
Machinability Index Comparison: 1010 vs 1018 vs 1020
Grade 1010 carries the highest machinability rating of all A519 carbon grades. The table below compares the three most commonly specified low-carbon A519 grades. When tool life and surface finish are the primary selection criteria, Grade 1010 is the clear choice. For applications requiring slightly more strength, see AISI 1018 Tubes & Pipes or ASTM A519 1020 Seamless Tube.
| Grade | Carbon % | Machinability Index (AISI 1212 = 100%) | Primary Application |
|---|---|---|---|
| ASTM A519 1010 | 0.08 - 0.13% | 65% | Bushings, liners, high-speed machined parts |
| ASTM A519 1018 | 0.15 - 0.20% | 58% | Shafts, pins, general machined components |
| ASTM A519 1020 | 0.18 - 0.23% | 52% | Structural tubing, weldable parts, cylinders |
Applications of ASTM A519 Grade 1010 Seamless Tube
The combination of ultra-low carbon content, high machinability, and excellent cold drawability makes Grade 1010 the preferred choice for the following end uses:
- Bushings and sleeve bearings in automotive and industrial assemblies
- Precision drawn liners for hydraulic and pneumatic cylinders
- High-speed screw machine parts requiring minimal tool changes
- Light automotive stampings and deep-drawn housings
- Structural tubing for light-load applications where welding and forming are required
- Cold-formed rollers and bobbin cores in textile machinery
- Case-hardened parts where a soft core and hard surface are required after carburizing
