FAQ:

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.
