Product Description

ASTM A403 WP321-S Stainless Steel 180 Degree U Bend/Elbow

Product Specifications

Attribute	Value
Product Name	180 Degree Return Bend/Elbow
Specification	ASTM A403
Material	WP321-S
Radius	LR or SR (Depend on Customer's Requirements)
Surface	Sand Tumbling or Sand Blasting
Test	Size Inspection, NDE Test
Size Standard	ASME B16.9
Application	Heat Exchangers, Piping Systems, Oil and Gas Industry, Water Treatment

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)

Element	Composition (% 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.

Mechanical Properties

Property	Value
Tensile Strength	≥ 515 MPa (75,000 psi)
Yield Strength (0.2% offset)	≥ 205 MPa (30,000 psi)
Elongation (in 2 inches)	≥ 35%
Hardness (Rockwell B)	≤ 95 HRB

Key Features

Exceptional high-temperature performance (up to 900°C/1650°F)
Superior corrosion and oxidation resistance
Seamless construction for high-pressure reliability
Excellent weldability with titanium stabilization

Industrial Applications

High-Temperature Systems: Heat exchangers, boilers, furnaces
Chemical Processing: Corrosive chemical handling, process piping
Power Generation: Steam lines, turbine bypass systems
Oil & Gas: Refinery piping, offshore platforms
Sanitary Industries: Food/pharmaceutical processing, CIP systems
