Pytania i odpowiedzi:
  • What are the main differences between Incoloy 800 and Incoloy 800H?
    Incoloy 800H has a controlled carbon content (0.05-0.10%) for improved creep rupture strength at high temperatures, while Incoloy 800 has a maximum carbon content of 0.10%. Both alloys share similar nickel, chromium, and iron compositions.
  • What industries commonly use Incoloy 800/800H welded pipes?
    These pipes are widely used in petrochemical, power generation, chemical processing, heat treatment, and nuclear industries for applications like heat exchanger tubes, boiler tubes, and reactor piping.
  • What welding methods are recommended for Incoloy 800/800H pipes?
    Recommended welding methods include TIG (GTAW), MIG (GMAW), and SAW. Filler metals like ERNiCr-3 (Inconel 82) and ENiCrFe-3 (Inconel 182) are compatible. Post-weld heat treatment is advised for stress relief.
