    Product Description

    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.

    180-Degree U Bend Characteristics
    • Shape: Tight U-shaped fitting with 180-degree turn
    • Design: Small radius for space-constrained installations
    • Applications: Heat exchangers, boiler systems, compact piping configurations
    180-Degree Elbow Characteristics
    • Shape: Gradual curved fitting with 180-degree direction change
    • Design: Larger radius for smoother flow transition
    • Applications: General piping systems, chemical processes, fluid handling systems
    Material Composition (Type 321 Stainless Steel)
    ElementComposition (% 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.
