    Stainless Steel Elbow A403 WP321H For High Temperature Piping Systems

    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)



    ElementContent (%)Function
    Carbon (C)≤ 0.08Controls strength & hardness
    Chromium (Cr)17.0–19.0Corrosion/oxidation resistance
    Nickel (Ni)9.0–12.0Austenite stability & toughness
    Manganese (Mn)≤ 2.00Deoxidization & sulfur control
    Silicon (Si)≤ 1.00Deoxidization & fluidity
    Phosphorus (P)≤ 0.045Impurity control
    Sulfur (S)≤ 0.030Machinability improvement
    Titanium (Ti)≥ 5xC minPrevents sensitization during welding
