A403 WP321 Return Bend Strength
The A403 WP321 Return Bend is a high-performance pipe fitting manufactured from WP321 stainless steel per ASTM A403 standard, designed for 180° directional changes in piping systems.
Key Characteristics
- Excellent high temperature oxidation and corrosion resistance
- Superior mechanical properties and weldability
- Titanium addition prevents chromium carbide precipitation, enhancing intergranular corrosion resistance
Strength Parameters
- Tensile Strength: ≥515 MPa (75,000 psi)
- Yield Strength: ≥205 MPa (30,000 psi)
- Elongation: ≥35% (within 50mm standard distance)
- Hardness range: HB ≤187 (Brinell hardness)
Strength Influencing Factors
- Wall thickness: Increased thickness enhances strength
- Manufacturing process: Seamless construction offers higher strength than welded
- Temperature: Maintains high strength at elevated temperatures with proper reduction factor consideration
Application Scenarios
- High temperature environments: boilers, heat exchangers, steam pipelines
- Corrosive media applications: chemical and petrochemical industries
- Systems requiring resistance to intergranular corrosion: post-weld piping systems
Strength Verification
- Test standards: ASTM A403 and ASME B16.9 compliance
- Hydraulic testing for pressure performance validation
- Tensile testing for strength verification
- Hardness testing for material standard compliance
Material Comparison
- vs Carbon Steel: Similar strength with enhanced corrosion and high temperature resistance
- vs 304 Stainless Steel: Comparable strength with superior intergranular corrosion resistance
- vs 316 Stainless Steel: Similar strength with 316 offering better pitting resistance
