INCOLOY® alloy 800H® is a controlled composition derivative of INCOLOY® alloy 800 (UNS N08800).  Applications have extended from petrochemical processing reformer tubing, to bellows and flare tips in refinery service. In power generation, superheater and reheater tubing has also employed the material. Heat treatment retorts, muffles jigs and fixtures have also used this material to great effect.
