ASTM B462 C276 UNS N10276 Nickel Alloy Weldneck(WN) Forged Flange Raised Face

ASTM B462 is Specification for Forged or Rolled Nickel Alloy Pipe Flanges, Forged Fittings, and Valves and Parts for Corrosive High-Temperature Service.

This product is a weldneck flange forged from Hastelloy C276 (UNS N10276) alloy in accordance with ASTM B462 standard. It features a welded neck design for butt-welding to piping and a Raised Face (RF) sealing surface. This forged flange is engineered for extreme corrosive service in industries such as chemical processing, oil & gas, marine, and flue gas desulfurization, leveraging the base material's outstanding resistance to both oxidizing and reducing media, chloride-induced stress corrosion cracking, pitting, and crevice corrosion. It is a critical component for ensuring the long-term safety and reliability of high-pressure, high-temperature, and mission-critical process piping systems.

2. Key Adventages

  • Exceptional Corrosion Resistance

Manufactured from Hastelloy C276 (UNS N10276), providing outstanding performance in both oxidizing and reducing media, with high resistance to chloride-induced stress corrosion cracking, pitting, and crevice corrosion.

  • High-Strength Forged Integrity

Strictly forged per ASTM B462, eliminating casting defects and providing continuous grain flow for superior mechanical strength, fatigue resistance, and impact toughness.

  • Reliability in High-Temperature & High-Pressure Service

Maintains excellent mechanical properties and creep resistance at elevated temperatures, suitable for demanding applications in chemical, oil & gas, and flue gas desulfurization systems.

  • Optimized Stress Distribution & Connection Safety

The weldneck design gradually transfers stress from the flange hub to the pipe, minimizing stress concentration and enhancing safety under long-term cyclic service.

  • Broad Media Compatibility & Long Service Life

Resistant to a wide range of corrosive media including sulfuric, hydrochloric, and phosphoric acids, chlorides, and seawater, significantly reducing maintenance needs and total cost of ownership.


3. Key Applications

  • Chemical Processing & Petrochemical Industry
  • Flue Gas Desulfurization (FGD) Systems
  • Pharmaceutical & Biotechnology
  • Pulp & Paper Industry
  • Waste Treatment & Energy Recovery
  • Marine & Seawater Applications
  • Nuclear Fuel Reprocessing
