Advantages of ASME SB407 UNS N08811
1. Outstanding High-Temperature Resistance
Can maintain stable mechanical properties at high temperatures
(e.g., 650–1093℃), resisting deformation/cracking under pressure,
ensuring pipeline stability.
2. Strong Corrosion Resistance
Resists oxidative acids (like nitric acid), sulfur-containing
media, and stress corrosion.
Reduces leakage risks, suits chemical, petrochemical high high-temp
corrosive environments.
3. Superior Structural & Quality Assurance
Seamless structure: Uniform wall thickness, no weak welds, ideal
for high-pressure/high-purity fluid transport.
Complies with ASME SB407: Strict tests (chemical, mechanical, non -
non-destructive) ensure reliable quality.
4. Good Processability
Easy to form: Can be cold/hot - worked into various shapes
(straight/bent tubes) for diverse design needs.
Friendly welding: Welds match base metal performance, cutting
installation/maintenance costs.
