Incoloy 800H, tseem hu ua "Alloy 800H", raug xaiv los ua UNS N08810 lossis DIN W.Nr. 1.4958 ib. Nws muaj yuav luag tib yam tshuaj muaj pes tsawg leeg xws li Alloy 800 tshwj tsis yog tias nws yuav tsum muaj cov pa roj carbon ntau ntxiv uas ua rau muaj kev txhim kho cov khoom kub. Piv rauKev 800, nws muaj kev nkag siab zoo dua thiab kev ntxhov siab-rupture yam ntxwv nyob rau hauv 1100 ° F [592 ° C] mus rau 1800 ° F [980 ° C] kub ntau yam. Thaum Incoloy 800 feem ntau yog annealed ntawm kwv yees li 1800 ° F [980 ° C], Incoloy 800H yuav tsum tau annealed ntawm kwv yees li 2100 ° F [1150 ° C]. Dhau li ntawd, Alloy 800H muaj ib coarser nruab nrab grain loj raws li ASTM 5.
