Description:

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. The carbon content of INCOLOY alloy 800 (UNS N08800) is 0.10% max with no limit on the lower end. The carbon content for INCOLOY alloy 800H (UNS N08810) is 0.05 to 0.10%, which is the upper end of the 0.10% maximum specified for INCOLOY alloy 800. The chemical limits for INCOLOY alloy 800HT (UNS N08811) are even more restrictive yet still within the limits specified for INCOLOY alloy 800H.
