Description
ASTM B564 UNS N10276 Nickel Alloy Forged Rings
High Strength & Corrosion Resistance for Industrial Applications
ASTM B564 UNS N10276 nickel alloy forged rings provide critical equipment with decades-long corrosion-resistant protection, fundamentally reducing the risk of corrosion leaks, minimizing unplanned downtime losses, extending equipment lifespan, and maximizing asset lifecycle value and operational efficiency.
Chemical Composition Control
UNS N10276's key element design achieves comprehensive corrosion resistance in both oxidation and reduction 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
Application Scenarios
C-276 forged rings are commonly used in the manufacture of critical connection components for high-pressure, highly corrosive environments:
  • Flanges and valves in petroleum refining plants
  • End caps and sealing rings in chemical reactors
  • Pressure vessel interfaces in seawater desalination systems
  • Pipeline connections in flue gas desulfurization (FGD) equipment
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
