SA179 is a specification for carbon steel seamless cold-drawn low-carbon steel heat-exchanger and condenser tubes. Here is a technical description of SA179 Carbon Steel tubing:

Composition: SA179 Carbon Steel tubing is primarily composed of iron (Fe) and carbon (C), with trace amounts of other elements such as manganese (Mn) and silicon (Si). The carbon content in SA179 tubing is typically kept low to enhance its weldability and to prevent the formation of brittle structures.

Mechanical Properties: The mechanical properties of SA179 Carbon Steel tubing can vary depending on the manufacturing process and heat treatment, but they generally exhibit the following characteristics:

  • Tensile Strength: Typically ranges from 325 MPa (47,000 psi) to 415 MPa (60,000 psi)
  • Yield Strength: Generally around 180-205 MPa (26,000-30,000 psi)
  • Elongation: Typically 35% minimum

Physical Properties:

  • Density: Approximately 7.85 g/cm³ (0.284 lb/in³)
  • Melting Point: Approximately 1420-1460°C (2588-2660°F)

Corrosion Resistance: SA179 Carbon Steel tubing is not known for its inherent corrosion resistance. However, it is commonly used in applications where corrosion resistance is not the primary concern. To enhance corrosion resistance, additional protective coatings or treatments can be applied to the tubing based on the specific application requirements.

Machinability: SA179 Carbon Steel tubing is generally considered to have good machinability. It can be easily machined using common techniques, including cutting, drilling, and turning. However, the exact machinability may vary depending on factors such as the manufacturing process, heat treatment, and specific alloying elements.
