I-ALLOY 800 • UNS N08800 • WNR 1.4876

I-alloy 800, 800H, kunye ne-800HT yi-nickel-iron-chromium alloys enamandla kunye nokuchasana okugqwesileyo kwi-oxidation kunye ne-carburization kwi-exposure high-temperature. Ezi nickel steel alloys ziyafana ngaphandle kwinqanaba eliphezulu lekhabhoni kwi-alloy 800H / HT kunye nokongeza ukuya kwi-1.20 yeepesenti ze-aluminium kunye ne-titanium kwi-alloy 800HT. I-800 yayiyeyokuqala kwezi ngxubevange kwaye yatshintshwa kancinane yaba yi-800H. Olu hlengahlengiso lwalulawula i-carbon (.05-.10%) kunye nobukhulu beenkozo ukuze kulungiswe iimpawu zokuqhawula uxinzelelo. Kwizicelo zonyango olushushu i-800HT inolunye uhlengahlengiso kumanqanaba adibeneyo e-titanium kunye ne-aluminium (.85-1.20%) ukuqinisekisa iipropati eziphezulu zeqondo lokushisa. I-alloy 800H/HT yenzelwe usetyenziso lwesakhiwo sobushushu obuphezulu. Umxholo we-nickel wenza ukuba ii-alloys zixhathise kakhulu kuzo zombini i-carborisation kunye ne-embrittlement ukusuka kwimvula yesigaba se-sigma.
