Product Description
High-Performance Nickel Alloy Forged Rings – ASTM B564 UNS N10276
ASTM B564 UNS N10276 nickel-based alloy forged rings deliver exceptional corrosion resistance and high-temperature strength for critical equipment operating under extreme conditions. These components are widely used in petrochemical, chemical processing, pollution control, and marine engineering applications where reliability and durability are paramount.
These forged rings provide decades of corrosion-resistant protection, significantly reducing the risk of corrosion leaks, minimizing unplanned downtime, extending equipment lifespan, and maximizing operational efficiency and asset lifecycle value.
Chemical Composition Control
UNS N10276's optimized element design provides comprehensive corrosion resistance in both oxidizing and reducing environments:
- Ni: Balance - matrix element providing high-temperature stability and basic corrosion resistance
- Molybdenum (Mo): 15.0-17.0% - core element for resistance to pitting and crevice corrosion, especially crucial in chlorine-containing media
- Chromium (Cr): 14.5-16.5% - enhances oxidation resistance against oxidizing acids such as nitric acid
- Tungsten (W): 3.0-4.5% - synergistically enhances solid solution strengthening with molybdenum, improving high-temperature strength
- Carbon (C): ≤0.010% - extremely low carbon design minimizes carbide precipitation during welding or heat treatment, reducing intergranular corrosion risk
Manufacturing Process
C-276 forged rings process route: Ingot casting → Free forging billet → Punching → Ring rolling → Finishing
Typical Application Scenarios
UNS N10276 forged rings are particularly suitable for the following harsh environments:
- Chemical and Petrochemical Industries: Reactor flanges, high-pressure valves, pump casings, and other components exposed to mixed acids (such as sulfuric acid + hydrochloric acid), organic acids (formic acid, acetic acid), and chloride media
- Pollution Control: Scrubbers, reheaters, fan blades, etc., in flue gas desulfurization systems, subject to long-term contact with wet sulfur- and chlorine-containing waste gases
- Marine and Seawater Desalination: Seawater pipeline systems, heat exchanger end caps, resisting pitting and crevice corrosion under high chloride ion concentrations
- Energy and Aviation: Valves in supercritical power plants, precision load-bearing components in aero-engines, requiring high fatigue life under dynamic loads
Quality Assurance and Procurement Recommendations
To ensure forged rings meet actual working conditions, the following measures are recommended:
- Clarify Technical Specifications: Specify standard version, chemical composition tolerances, mechanical property classification, heat treatment status, and non-destructive testing requirements (ultrasonic + penetrant testing) in procurement contracts
- Select Qualified Suppliers: Prioritize manufacturers with vacuum induction melting + electroslag remelting (VIM+ESR) capabilities to ensure material purity
- Key Points for Delivery Acceptance:
- Verify chemical composition and mechanical property data in Material Quality Certificate (MTC)
- Implement PMI (Positive Material Identification) sampling inspections to verify material authenticity
- Check surface treatment quality, perform pickling or sandblasting if necessary to remove oxide scale
