ASTM A213 T92 (ASME SA213 T92)ni umuyoboro w'icyuma gikozwe muri chromium alloy ifite umugozi mwinshi, urimo 8.5–9.5% Cr, 0.2–0.5% W na Mo, V, Nb, n'ibindi bintu bivangavanze.Nyuma yo kuvugurura no gushyushya, uyu muyoboro w'icyuma ufite imbaraga nyinshi mu bushyuhe bwinshi, urwanya cyane gucika kw'amazi, kandi ukagira ubushyuhe buhamye.
Imiyoboro y'icyuma ya T92 ikunze gukoreshwa mu bice by'ingenzi bya boilers zifite umuvuduko mwinshi n'umuvuduko mwinshi cyane, imashini zihindura ubushyuhe, n'imashini zishyushya cyane, kandi ikoreshwa cyane mu nganda zitanga ingufu, peteroli, n'ingufu.
Nomero ya UNS ni K92460.
Botop Steelni umucuruzi w’umwuga kandi wizewe w’imiyoboro y’ibyuma bya alloy mu Bushinwa, ushobora guha imishinga yawe vuba imiyoboro y’ibyuma by’ubwoko butandukanye, harimoT5 (K41545), T9 (K90941),T11 (K11597),T12 (K11562),T22 (K21590), naT91 (K90901).
Ibicuruzwa byacu bifite ubuziranenge bwizewe, igiciro cyabyo kiri mu irushanwa, kandi bishyigikira igenzura ry’abandi.
Ibisabwa ku miterere ya T92 birakomeye cyane. Kugenzura neza ibintu by'ingenzi nka C, Cr, Mo, W, V, Nb, B, na N bigenzura imikorere rusange y'imiyoboro y'icyuma. Isuzuma ry'imiterere ya chimique rigomba gukorwa hakurikijwe ibisabwa na ASTM A1016.
