Detail

Incoloy* 800H/HT (UNSN08810/N08811)

Introduction

INCOLOY 800H and 800HT have  significantly higher creep and rupture strength than INCOLOY 800. The three  alloys have nearly identical chemical composition limits. 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 800 (UNS N08800)  is 0.10% max with no limit on the lower end. The carbon content for INCOLOY 800H  (UNS N08810) is 0.05 to 0.10%, which is the upper end of the 0.10% maximum  specified for INCOLOY 800. The chemical limits for INCOLOY alloy 800HT (UNS  N08811) are even more restrictive yet still within the limits specified for INCOLOY  alloy 800H. The carbon content for INCOLOY alloy 800HT is further restricted  to 0.06 – 0.10%. Additionally, the Al plus Ti content of INCOLOY alloy 800HT  is restricted to 0.85 – 1.20%. Note that the chemical compositions for  INCOLOY alloy 800HT will always be within the limits of INCOLOY alloy 800H. Note  also that the limits for INCOLOY alloy 800H may or may not be within the  limits of INCOLOY 800HT
