A403 WP321H Stainless Steel Elbows are ASME B16.9/B16.25 compliant butt-weld fittings engineered for extreme environments. The addition of Titanium (Ti) stabilizes the alloy against carbide precipitation, making it ideal for continuous high-temperature service (450°C–900°C) and corrosive media. These elbows are solution-annealed & quenched to maximize intergranular corrosion resistance in acidic, chloride-rich, and oxidizing conditions.
Superior Heat Resistance – Maintains structural integrity up to 900°C
Stress Corrosion Cracking (SCC) Resistance – Critical for chemical/petrochemical applications
ASTM A403 & ASME B16.9 Certified – Guaranteed dimensional/tolerance compliance
Weld-Ready Design – Beveled ends ensure full-penetration weld integrity

| Chromium (Cr) | 17.0–19.0 | Corrosion/oxidation resistance |
| Nickel (Ni) | 9.0–12.0 | Austenite stability & toughness |
| Manganese (Mn) | ≤ 2.00 | Deoxidization & sulfur control |
| Silicon (Si) | ≤ 1.00 | Deoxidization & fluidity |
| Phosphorus (P) | ≤ 0.045 | Impurity control |
| Sulfur (S) | ≤ 0.030 | Machinability improvement |
| Titanium (Ti) | ≥ 5xC min | Prevents sensitization during welding |
