A403 WP321H Stainless Steel Elbow - High-Temperature Corrosion Resistant Pipe Fitting


Product Introduction


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.


Key Advantages


 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


Chemical Composition (ASTM A403 WP321H)



Element Content (%) Function
Carbon (C) ≤ 0.08 Controls strength & hardness
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
