Ukupakisha: ibhegi elukiweyo ebotshelelweyo / ibhokisi yeplywood / ukupakisha ibhokisi yomthi ngaphandle
Amagqabaza: Umbhobho wentsimbi engagqwaliyo ongekho semgangathweni ungenziwa ngokwezifiso ngokweemfuno zabathengi
I-253MA (UNS S30815) yintsimbi engagqwaliyo enganyangekiyo egqunywe bubushushu eyenzelwe usetyenziso olufuna amandla aphezulu okurhubuluza kunye nokumelana okuhle nokugqwala. Ubushushu bayo bokusebenza buyi-850~1100 °C.
Ulwakhiwo lweekhemikhali lwe-253MA lulungelelene, nto leyo eyenza ukuba intsimbi ibe nokusebenza okugqibeleleyo okufanelekileyo kuluhlu lobushushu oluphakathi kwe-850°C-1100°C, ukumelana okuphezulu kakhulu kwe-oxidation, ubushushu be-oxidation ukuya kuthi ga kwi-1150°C, kunye nokumelana okuphezulu kakhulu kwe-creep. Amandla kunye namandla okuqhekeka kwe-creep; ukumelana okugqwesileyo kwi-corrosion ephezulu kunye nokumelana ne-brush corrosion kwiindawo ezininzi zegesi; amandla aphezulu okuvelisa kunye namandla okutsalwa kubushushu obuphezulu; ukwakheka okuhle kunye nokudityaniswa, kunye nokusebenza ngokwaneleyo koomatshini.
Ukongeza kwizinto ezidibanisa i-chromium kunye ne-nickel, intsimbi engagqwaliyo ye-253MA ikwanayo nenani elincinci leentsimbi zomhlaba ezinqabileyo, ngaloo ndlela iphucula kakhulu amandla ayo okulwa ne-antioxidant. I-nitrogen yongezwa ukuphucula iipropati zokuqhekeka nokwenza le ntsimbi ibe yi-austenite ngokupheleleyo. Nangona umxholo we-chromium kunye ne-nickel uphantsi kakhulu, ezi ntsimbi zingagqwaliyo kwiimeko ezininzi zineempawu ezifanayo zobushushu obuphezulu njengeentsimbi ze-alloy ezixutywe kakhulu kunye nee-alloys zesiseko se-nickel.
