Description
Incoloy 800HT
INCOLOY alloys 800H and 800HT have significantly higher creep and rupture strength than INCOLOY alloy 800.The three alloys have nearly identical chemical composition limits. As Table 1 shows, the base elements in all three alloys are the same. However, chemical composition limits vary with carbon, aluminum and titanium.
