Mild steel tubes are widely used in various industries due to their excellent mechanical properties, durability, and affordability. Three popular mild steel tube grades are AISI 1020, 4130, and 4140. In this article, we will discuss the material, specification, chemical composition, mechanical properties, steel grade, and application of these three grades.
AISI 1020 is a low-carbon steel that contains 0.18% carbon and 0.23% manganese. It is known for its excellent machinability and weldability.
The ASTM A519 specification covers several grades of carbon and alloy steel mechanical tubing, including AISI 1020. The standard specification for seamless carbon and alloy steel mechanical tubing is ASTM A519/A519M.
| Element | Composition (%) |
|---|---|
| Carbon | 0.18 |
| Manganese | 0.23 |
| Phosphorus | 0.04 max |
| Sulfur | 0.05 max |
| Property | Value |
|---|---|
| Tensile strength | 420 MPa |
| Yield strength | 350 MPa |
| Elongation | 15% |
AISI 1020 is a low-carbon steel grade that is widely used in the manufacturing of various mechanical components, such as gears, axles, and shafts.
AISI 1020 mild steel tubes are commonly used in applications that require high precision and excellent machinability, such as automotive parts, hydraulic cylinders, and machine tools.
AISI 4130 is a low-alloy steel that contains chromium and molybdenum. It has excellent strength and toughness, making it an ideal material for high-stress applications.
The ASTM A519 specification covers several grades of carbon and alloy steel mechanical tubing, including AISI 4130. The standard specification for seamless carbon and alloy steel mechanical tubing is ASTM A519/A519M.
| Element | Composition (%) |
|---|---|
| Carbon | 0.28-0.33 |
| Chromium | 0.8-1.1 |
| Manganese | 0.4-0.6 |
| Molybdenum | 0.15-0.25 |
| Property | Value |
|---|---|
| Tensile strength | 560 MPa |
| Yield strength | 460 MPa |
| Elongation | 20% |
AISI 4130 is a low-alloy steel grade that is commonly used in the manufacturing of aircraft components, such as landing gear and engine parts.
AISI 4130 mild steel tubes are widely used in the aerospace industry, as well as in the manufacturing of high-stress components, such as shafts, gears, and cylinders.
