I-alloy ye-253Ma inezi mpawu zilandelayo:
I-253MA yintsimbi ye-austenitic enganyangekiyo ukumelana nobushushu eyenzelwe usetyenziso olufuna amandla aphezulu okurhubuluza kunye nokuxhathisa okulungileyo ekudlekeni.Umgangatho wobushushu osebenzayo yi-850 ~ 1100 °C.
Ukubunjwa kweekhemikhali ze-253MA zilungelelene, okwenza ukuba intsimbi ibe neyona nto ifanelekileyo ifanelekileyo kwiimpawu zokushisa kwe-850 ° C-1100 ° C, ukuxhatshazwa kwe-oxidation ephezulu kakhulu, kunye nobushushu bomlinganiselo ukuya kwi-1150 ° C;uxhathiso oluphezulu kakhulu lokurhubuluza Isakhono kunye namandla okugqabhuka okurhubuluza;ukuxhathisa okulungileyo kwi-corrosion ephezulu yokushisa kunye nokuchasana kwi-brashi ye-corrosion kumajelo amaninzi e-gaseous;amandla aphezulu esivuno kunye namandla okuqina kumaqondo obushushu aphezulu;formability elungileyo kunye weldability Kwaye machinability ngokwaneleyo.
Ukongeza kwizinto ezidibanisa i-chromium kunye ne-nickel, i-253MA yensimbi engenasici iqulethe ixabiso elincinci lesinyithi esinqabileyo somhlaba (i-Rare Earth Metals, i-REM), ephucula kakhulu amandla ayo e-antioxidant.I-nitrojeni yongezwa ekuphuculeni iipropati ze-creep kunye nokwenza le ntsimbi ibe yi-austenite epheleleyo.Nangona iziqulatho ze-chromium kunye ne-nickel ziphantsi kakhulu, le ntsimbi ingenasici ineempawu ezininzi zobushushu obuphezulu njengentsimbi yealloyi ephezulu kunye ne-nickel-based alloy.
253Ma izicelo:
I-253MA isetyenziswe ngokubanzi kwizixhobo zokutshiza, izixhobo zokutshisa i-furnace, ukunyibilika kwensimbi, isithando somlilo kunye nezixhobo eziqhubekayo zokuphosa, ii-mill rolling (iziko ezifudumalayo), izixhobo zokunyanga ukushisa kunye nezixhobo, izixhobo zamaminerali kunye nezixhobo zokuvelisa i-samente.
