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.
