ASTM A213 T92 (ASME SA213 T92)ndi chitoliro chachitsulo chopanda msoko chokhala ndi chromium alloy, chokhala ndi 8.5–9.5% Cr, 0.2–0.5% W ndi Mo, V, Nb, ndi zinthu zina zophatikizira.Pambuyo pokonzanso ndi kutenthetsa, chitoliro chachitsulo ichi chimakhala ndi mphamvu yotentha kwambiri, kukana kuyandama bwino, komanso kukhazikika bwino kwa kutentha.
Mapaipi achitsulo a T92 amagwiritsidwa ntchito kwambiri pazinthu zofunika kwambiri za ma boiler okhala ndi mphamvu yamagetsi komanso yamagetsi amphamvu kwambiri, zosinthira kutentha, ndi ma superheater, ndipo amagwiritsidwa ntchito kwambiri m'mafakitale amagetsi, petrochemical, ndi mphamvu.
Nambala ya UNS ndi K92460.
Chitsulo cha Botopndi katswiri komanso wodalirika wogulitsa mapaipi achitsulo cha alloy komanso wogulitsa zinthu zambiri ku China, wokhoza kupereka mwachangu mapulojekiti anu mapaipi achitsulo cha alloy osiyanasiyana, kuphatikizaT5 (K41545), T9 (K90941),T11 (K11597),T12 (K11562),T22 (K21590)ndiT91 (K90901).
Zogulitsa zathu ndi zapamwamba kwambiri, zimakhala ndi mitengo yopikisana, ndipo zimathandiza kuyang'aniridwa ndi anthu ena.
Zofunikira pa kapangidwe ka mankhwala a T92 n'zokhwima kwambiri. Kuwongolera bwino zinthu zofunika monga C, Cr, Mo, W, V, Nb, B, ndi N kumaonetsetsa kuti mapaipi achitsulo akuyenda bwino. Kuyesa kapangidwe ka mankhwala kuyenera kuchitika motsatira zofunikira za ASTM A1016.
