Product Description

ASTM A403 WP321H-S 180° Return Bends: High-Temp Resistant Stainless Steel for Furnace Piping

 

Yuhong Holding Group presents ASTM A403 WP321H-S 180° return bends, engineered for critical furnace connections in corrosive and high-temperature environments. These elbows ensure seamless flow in finned tube systems, combining durability with precision performance.

 

Material & Chemistry
Crafted from TP321H-S stainless steel, stabilized with titanium to resist carbide precipitation, ideal for elevated temperatures:

 

Type  Radius Size Range
Short Radius R=1.0 x Nominal Dia. 1/2" - 24"
Customized As per requirement Available

 

 

Chemical Composition:

 

Element C Mn P S Si Cr Ni
% 0.04-0.10 ≤2.00 ≤0.045 ≤0.03 ≤1.00 17-19 9-12

 

 

Mechanical Properties:

​

Property
Tensile Strength
Yield Strength
Elongation
Max Operating Temp
Corrosion Resistance
Value
≥515 MPa
≥205 MPa
≥30%
870°C
Excellent in oxidizing environments

 

Manufacturing & Design
 
  • Precision Forging: Ensures uniform wall thickness and tight radius tolerance (1.5D standard).
  • Solution Annealing: 925–1010°C heat treatment enhances grain structure for high-temperature stability.
  • HF Weld Compatibility: Matches finned tube systems with seamless integration in heater circuits.

 

Applications
 
Perfect for:
  • Industrial furnace radiant coils
  • Petrochemical reformer units
  • Waste heat recovery systems
  • Corrosive gas pipelines

Key Advantages

  • Carbide Stability: Titanium addition prevents intergranular corrosion under cyclic heating.
  • Thermal Fatigue Resistance: Handles rapid temperature fluctuations common in furnace operations.
  • Dimensional Accuracy: Tight tolerances reduce flow turbulence and pressure drop.

FAQ

Q: Can these bends be used with acidic fuels?
A: Yes, TP321H-S resists sulfuric and nitric acid corrosion typical in industrial exhaust.
Q: What sizes are available?
A: Standard sizes ½"–12", with custom dimensions for specific furnace layouts.
