UNS N06455 (CR HC 4 / Hastelloy C-4 / W. Nr. 2.4610)
UNS N06455, widely recognized as Hastelloy C-4 (or Alloy C-4), is a versatile nickel-chromium-molybdenum alloy characterized by its excellent high-temperature stability, particularly its resistance to the formation of deleterious grain boundary precipitates in the weld heat-affected zone. This critical feature minimizes the risk of intergranular corrosion after welding, making it highly suitable for fabricated chemical process equipment. Its chemical composition includes significant amounts of chromium (approx. 16%) and molybdenum (approx. 16%), which provide outstanding corrosion resistance to a variety of severe media. Key properties include:
Excellent High-Temperature Stability: Superior resistance to grain boundary precipitation and embrittlement in the 650 to 1040°C (1200 to 1900°F) range, even after prolonged exposure.
Outstanding Corrosion Resistance: Provides superb resistance to strong oxidizing agents (like ferric and cupric chlorides), hot contaminated mineral acids, solvents, and aggressive chloride solutions.
Good Resistance to Stress Corrosion Cracking (SCC): Offers reliability in a broad range of chemical process streams.
Resistance to Pitting & Crevice Corrosion: Effective against localized corrosion in various aggressive media.
Good Weldability & Formability: Low carbon content and high thermal stability allow for use in the as-welded condition in many applications without risk of intergranular corrosion.
Our ASTM B366 WPHC4 fittings ensure robust and reliable connections, maintaining system integrity in critical process piping where excellent high-temperature stability and comprehensive corrosion resistance in diverse chemical environments are paramount.
