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.
