About Incoloy® 800H

Incoloy 800h also belongs to nickel-iron-chromium alloy family alike alloy 800 & 800ht. All three variant has almost identical chemical composition. Alloy 800h has high creep rupture properties than alloy 800. Carbon content of alloy 800h has been restricted to 0.05-0.10%. In addition to carbon restriction, incoloy 800h receives a high-temperature annealing treatment that produced an average grain size of ASTM 5 or coarser. Overall the annealing treatment and carbon content restriction are responsible for alloy 800h having higher creep and rupture strength. Incoloy 800h is also extensively used for bolting in petrochemical and allied industries.
