Ukusebenza Kokugqwala
Ipuleti le-S32760 lisetshenziswa lapho kudingeka khona ukumelana nokugqwala okuphezulu endaweni ethile ezindaweni eziqukethe i-chloride. Ukwengezwa kwe-chromium, i-molybdenum, i-nitrogen, i-tungsten kanye nethusi kunikeza ukumelana okuqinile ekugqwaleni kwemigodi kanye ne-crevice uma kuqhathaniswa namazinga ajwayelekile e-duplex.
Ukwenziwa
I-S32760 ingasikwa, yakhiwe futhi isetshenziswe ngomshini ngamathuluzi afanele kanye nokulawula inqubo. Ngenxa yamandla ayo aphezulu kanye nesakhiwo sayo esiphindwe kabili, imithwalo yokwakha ingaba phezulu kunensimbi engagqwali ye-austenitic, futhi izinqubo zokushisela kufanele zilawule ukufakwa kokushisa kanye nokushisa okuphakathi.
Ukushisela
Ukushisela kungenziwa ngezinqubo ezifanele kanye nezinsimbi zokugcwalisa ezihambisanayo. Indawo yokushisela eqediwe kufanele igcine ibhalansi efanele ye-ferrite-austenite kanye nokumelana nokugqwala. Ukuhlanza ngemva kokushisela, ukuthosa noma ukudlulisa umoya kungadingeka kuye ngezimo zesevisi.
Ukwelashwa Kokushisa
I-S32760 ivame ukunikezwa isesimweni esifakwe isixazululo. Ayikhethelwa ukuqinisa imvula. Ukuvezwa okungalungile kokushisa kungabangela imvula eyingozi yesigaba se-intermetallic, ngakho-ke ukwelashwa kokushisa kanye nokwenziwa kokushisa kufanele kulandele imininingwane nenqubo efanele.
