The ASTM A179 Low Carbon Steel Tube is a seamless cold-drawn low-carbon steel tube specifically designed for use in heat-exchanger applications. This tube is widely used in various industries where heat exchange is required, thanks to its excellent thermal conductivity and corrosion resistance. In this article, we will explore the material, specifications, key features, chemical composition, mechanical properties, steel grades, applications, possible alternative grades, and more.
ASTM A179 specifies the requirements for seamless cold-drawn low-carbon steel tubes for heat-exchangers. These tubes are manufactured with precision using high-quality steel, ensuring a seamless and reliable product. The material composition, tensile strength, hardness, and dimensional specifications are carefully defined to ensure optimal performance in heat-exchanger applications.
The ASTM A179 Low Carbon Steel Tube offers several key features that make it an ideal choice for heat-exchanger applications:
The following table presents the chemical composition of ASTM A179 Low Carbon Steel Tube:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.06 - 0.18 |
| Manganese (Mn) | 0.27 - 0.63 |
| Phosphorus (P) | 0.035 (max) |
| Sulfur (S) | 0.035 (max) |
| Silicon (Si) | 0.10 - 0.35 |
The table below highlights the mechanical properties of ASTM A179 Low Carbon Steel Tube:
| Property | Value |
|---|---|
| Tensile Strength | 325 MPa (min) |
| Yield Strength | 180 MPa (min) |
| Elongation | 35% (min) |
| Hardness (Rockwell B) | 72 HRB (max) |
ASTM A179 specifies only one steel grade, which is Grade A. This grade meets the specified chemical composition and mechanical property requirements, making it suitable for heat-exchanger applications.
The ASTM A179 Low Carbon Steel Tube finds extensive application in various heat-exchanger systems, including:
Its reliable performance, high thermal conductivity, and corrosion resistance make it an excellent choice for efficient heat exchange in these industries.
While ASTM A179 Grade A is the primary steel grade specified, some alternative grades might be suitable for specific applications. These alternative grades include:
These alternative grades should be carefully evaluated based on specific requirements to ensure compatibility and performance in the intended application.
