Incoloy 800H / 800HT Pipe

Incoloy 800H and 800HT is a nickel-iron-chromium alloy, which has very good strength and excellent oxidation resistance and carburization in high temperature environment. These nickel steel alloys are indistinguishable except for the large amount of carbon in the 800H alloy and the expansion of up to 1.20% aluminum and titanium in the 800HT alloy. Incoloy 800 was the first of these alloys, which was changed to Incoloy 800H. This change is to control carbon (.05-.10%) and grain size to improve stress rupture properties. The consolidation level of titanium and aluminum (.85-1.20%) was further adjusted Incoloy 800HT to ensure ideal high temperature performance.
