ASTM A403 WP321-S refers to a high-performance stainless steel fitting designed for piping systems requiring exceptional corrosion resistance and high-temperature stability. The 180-degree configuration enables complete flow reversal, making it ideal for demanding industrial applications.
| Element | Composition (% by weight) |
|---|---|
| Carbon (C) | ≤ 0.08% |
| Manganese (Mn) | ≤ 2.00% |
| Phosphorus (P) | ≤ 0.045% |
| Sulfur (S) | ≤ 0.030% |
| Silicon (Si) | ≤ 1.00% |
| Chromium (Cr) | 17.00% - 19.00% |
| Nickel (Ni) | 9.00% - 12.00% |
| Titanium (Ti) | ≥ 5 × (C%) (min. 0.10%) |
| Iron (Fe) | Balance |
Titanium stabilization prevents chromium carbide formation during welding or high-temperature exposure, enhancing intergranular corrosion resistance.
| Property | Value |
|---|---|
| Tensile Strength | ≥ 515 MPa (75,000 psi) |
| Yield Strength (0.2% offset) | ≥ 205 MPa (30,000 psi) |
| Elongation (in 2 inches) | ≥ 35% |
| Hardness (Rockwell B) | ≤ 95 HRB |
