Incoloy 800H Ni-Fe-Cr Alloy Welding Wire
Incoloy 800H Ni-Fe-Cr Alloy Welding Wire Introduction
Incoloy 800H is similar to alloy 800 but with improved creep and stress-rupture properties for applications above 650 °C (1200 °F). Resistant to high-temperature oxidation, carburization, and nitridation, it is widely used in petrochemical and thermal processing.
Incoloy 800HT is similar to alloy 800H but with even more precisely controlled composition.
Alloys 800H and 800HT are the standard materials for intermediate temperatures (620–925 °C, or 1150–1700 °F). These alloys combine corrosion resistance with strength and metallurgical stability. Major applications include hydrogen reformer manifolds and pigtail piping, ethylene dichloride furnace tubing, transfer piping, and high-temperature pressure vessels.
