ASTM A519 1020 Tubes | Low Carbon & Low Tensile Seamless Steel Tubing
ASTM A519 1020 tubes are widely used low carbon / low tensile seamless steel tubes known for their excellent machinability, good weldability, and reliable mechanical performance. These tubes are manufactured as per ASTM A519 standard and are made from ASTM SAE AISI 1020 carbon steel, a material valued across multiple industries for its balanced strength and ductility.
As experienced ASTM A519 1020 steel tubes manufacturers in India, we supply tubing that meets strict dimensional accuracy, surface finish, and mechanical property requirements. Our ASTM A519 Grade 1020 tubing is widely used in automotive, engineering, construction, and mechanical applications where consistent quality matters.
What is ASTM A519 Grade 1020 Carbon Steel?
ASTM A519 is a standard specification for seamless carbon and alloy steel mechanical tubing. Grade 1020 indicates a low carbon steel composition with approximately 0.20% carbon, making it easy to form, weld, and machine.
ASTM SAE AISI 1020 carbon steel is preferred when moderate strength, toughness, and cost efficiency are required.
Hot Rolled vs Cold Drawn AISI 1020 Steel Tubes
Hot Rolled 1020 Steel Properties
- Lower cost
- Slightly rough surface
- Suitable for structural and general-purpose use
AISI 1020 Cold Drawn Steel
- Smooth surface finish
- Tight dimensional tolerance
- Better machinability
- Ideal for precision automotive and engineering parts

Chemical Composition of ASTM SAE AISI 1020 Carbon Steel
The chemical composition defines why ASTM 1020 steel offers excellent weldability and forming ability.
ASTM A519 SAE 1020 – Chemical Composition Chart (%)
| Element | Composition (%) |
| Carbon (C) | 0.18 – 0.23 |
| Manganese (Mn) | 0.30 – 0.60 |
| Phosphorus (P) | ≤ 0.040 |
| Sulfur (S) | ≤ 0.050 |
| Iron (Fe) | Balance |
This controlled chemistry ensures low carbon / low tensile characteristics, making the steel suitable for cold drawing and machining operations.
Mechanical Properties of SAE 1020 Steel Tubes
The mechanical performance of ASTM A519 SAE1020 seamless tubing is ideal for components that require strength without brittleness.
SAE 1020 Steel Properties – Mechanical Chart
| Property | Typical Value |
| Tensile Strength | 420 – 500 MPa |
| SAE 1020 Yield Strength | ≥ 350 MPa |
| Elongation | ≥ 15% |
| Hardness | 120 – 180 HB |
| Impact Resistance | Good |
These values may vary slightly depending on whether the tube is hot rolled or cold drawn.
