Chemical Composition & Mechanical Properties
To ensure maximum oxidation resistance, our TP310S tubing strictly adheres to the following chemical and physical standards:
Chemical Analysis (%)
- Chromium (Cr): 24.0 – 26.0% (Provides excellent corrosion resistance)
- Nickel (Ni): 19.0 – 22.0% (Ensures high-temperature strength)
- Carbon (C): ≤ 0.08% (Reduces carbide precipitation during welding)
Mechanical Strength
- Tensile Strength: ≥ 515 MPa
- Yield Strength: ≥ 205 MPa
- Elongation: ≥ 35%
