Ukupakisha: isikhwama esilukiwe esihlanganisiwe / ibhokisi le-plywood / ukupakisha ibhokisi lokhuni elithunyelwe ngaphandle
Amazwana: Ipayipi lensimbi engagqwali elingeyona ejwayelekile lingenziwa ngezifiso ngokuya ngezidingo zamakhasimende
I-253MA (UNS S30815) iyinsimbi engagqwali ye-austenitic engagqwali engamelana nokushisa eyenzelwe izinhlelo zokusebenza ezidinga amandla aphezulu okukhukhuleka kanye nokumelana okuhle nokugqwala. Izinga layo lokushisa lokusebenza lingu-850~1100 °C.
Ukwakheka kwamakhemikhali kwe-253MA kuyalinganisela, okwenza insimbi ibe nokusebenza okuphelele okufaneleka kakhulu ebangeni lokushisa elingu-850°C-1100°C, ukumelana okuphezulu kakhulu kwe-oxidation, izinga lokushisa le-oxidation kufika ku-1150°C, kanye nokumelana okuphezulu kakhulu kwe-creep. Amandla kanye namandla okuqhekeka kwe-creep; ukumelana okuhle kakhulu nokugqwala kwezinga lokushisa eliphezulu kanye nokumelana nokugqwala kwebhulashi ezindaweni eziningi zegesi; amandla aphezulu okukhiqiza kanye namandla okudonsa emazingeni okushisa aphezulu; ukwakheka okuhle kanye nokushibilika, kanye nokusebenza okwanele kwemishini.
Ngaphezu kwezinto ezihlanganisa i-chromium ne-nickel, insimbi engagqwali engu-253MA iqukethe nenani elincane lezinsimbi zomhlaba ezingavamile, ngaleyo ndlela ithuthukisa kakhulu amandla ayo okulwa ne-antioxidant. I-nitrogen iyengezwa ukuthuthukisa izakhiwo zokuqhekeka nokwenza le nsimbi ibe yi-austenite ngokuphelele. Nakuba okuqukethwe yi-chromium ne-nickel kuphansi kakhulu, izinsimbi ezinjalo ezingagqwali ezimweni eziningi zinezakhiwo ezifanayo zokushisa okuphezulu njengezinsimbi ze-alloy ezixutshwe kakhulu kanye nezinsimbi zesisekelo se-nickel.
