| Manganese (Mn) | 0.30 - 0.90 |
| Silicon (Si) | 0.10 - 0.35 |
| Phosphorus (P) | 0.040 (max) |
| Sulfur (S) | 0.050 (max) |
Mechanical Properties
The mechanical properties of the carbon steel pipe are crucial for assessing its strength, ductility, and overall performance in auto refrigeration systems. The table below presents the typical mechanical properties of the carbon steel pipe:
| Property | Value |
| Tensile Strength | 415 MPa (min) |
| Yield Strength | 240 MPa (min) |
| Elongation | 30% (min) |
| Hardness (HB) | 197 (max) |
| Impact Toughness | 27 J (min) |
Steel Grade
The carbon steel pipe specified by ASTM A530 for auto refrigeration applications is typically available in various steel grades, including:
- ASTM A530 Grade A
- ASTM A530 Grade B
- ASTM A530 Grade C
The choice of steel grade depends on specific requirements such as strength, corrosion resistance, and temperature tolerance.
Application
