Incoloy 800H, uga dikenal minangka "Alloy 800H", ditetepake minangka UNS N08810 utawa DIN W.Nr. 1.4958. Komposisi kimia sing meh padha karo Alloy 800 kajaba mbutuhake tambahan karbon sing luwih dhuwur sing nyebabake sifat suhu dhuwur sing luwih apik. Dibandhingake karoIncoloy 800, nduweni ciri creep lan stress-rupture sing luwih apik ing kisaran suhu 1100°F [592°C] nganti 1800°F [980°C]. Nalika Incoloy 800 biasane anil ing kira-kira 1800°F [980°C], Incoloy 800H kudu anil ing kira-kira 2100°F [1150°C]. Kajaba iku, Alloy 800H duwe ukuran gandum rata-rata sing luwih kasar miturut ASTM 5.
