ALLOY 800 • UNS N08800 • WNR 1.4876
ʻO Alloy 800, 800H, a me 800HT nā nickel-iron-chromium alloys me ka ikaika maikaʻi a me ke kūpaʻa maikaʻi loa i ka oxidation a me ka carburization i ka ʻike wela kiʻekiʻe. ʻO kēia mau mea hao nickel he ʻano like koe wale nō ka pae kiʻekiʻe o ke kalapona i loko o ka alloy 800H/HT a me ka hoʻohui ʻana i ka 1.20 pakeneka alumini a me ka titanium i ka alloy 800HT. ʻO 800 ka mea mua o kēia mau ʻāpana a ua hoʻololi iki ʻia i 800H. ʻO kēia hoʻololi ʻana e hoʻomalu i ke kalapona (.05-.10%) a me ka nui o ka palaoa e hoʻomaikaʻi i nā waiwai rupture stress. Ma nā noi ho'ōla wela 800HT he mau hoʻololi hou aʻe i ka hui ʻana o ka titanium a me nā pae alumini (.85-1.20%) e hōʻoia i nā waiwai wela kiʻekiʻe. Ua manaʻo ʻia ʻo Alloy 800H/HT no nā noi hoʻolālā kiʻekiʻe. ʻO ka maʻiʻo nickel ka mea e kūpaʻa loa ai nā alloys i ka carborization a me ka embrittlement mai ka ua o ka pae sigma.
