Answer
17-7PH (UNS S17700) nigice cya austenitike yimvura-ikomera ibyuma bitagira umwanda bitanga imbaraga nyinshi kandi birwanya ruswa. Muburyo CH900, ibikoresho bikonje bikagabanuka kumiterere C hanyuma bigakomera imyaka $ 900 ^ {\ umuzenguruko} F $ ($ 482 ^ {\ umuzenguruko} C $). Iyi nzira ihindura austenite kuri martensite binyuze mumirimo ikonje hanyuma ikagusha icyiciro cya aluminiyumu ikungahaye. Imbaraga zitanga umusaruro mubisanzwe urenga $ 200 $ ksi. Ku masoko y'amazi, iyi mipaka ihanitse ya elastike ituma gutandukana gukomeye nta gushiraho bihoraho. Ariko, abashushanya ibintu bagomba kwitondera ibintu byoroshye guhura nibishobora kwangirika (SCC) mugihe bahuye na chloride mugihe bahangayitse cyane. Byongeye kandi, umunaniro ntarengwa muri CH900 utezimbere no gukwirakwiza imvura igwa neza, bigatuma iruta 302/304 idafite umwanda mwinshi wo kwipakurura ibintu bikurura indege.
