I-316L insimbi engagqwali iyinto eguquguqukayo futhi ehlala isikhathi eside esetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile. Lolu hlobo lwensimbi engagqwali luyaziwa ngokusebenza kwalo okuphezulu ezindaweni ezishisa kakhulu izinga lokushisa, kanye nokumelana nokungezwani komzimba nokuqina. Ake sijule ekutheni yini eyenza insimbi engagqwali engu-316L ibe into emangalisayo.
Okokuqala nokubaluleke kakhulu, insimbi engagqwali engu-316L iyinhlobonhlobo yekhabhoni ephansi engu-316 yensimbi engagqwali, okwenza kube ukukhetha okuhle kwezinhlelo zokusebenza ezidinga ukushiselwa. I-"L" ku-316L imele "low," okubonisa okuqukethwe kwekhabhoni encishisiwe ku-alloy. Lesi sici asigcini nje ngokuthuthukisa ukushisela kwezinto kodwa futhi sinciphisa ubungozi bemvula ye-carbide ezindaweni ezithinteke ukushisa ngesikhathi sokushisela, okungaholela ekugqwaleni kwe-intergranular.
Esinye sezici ezibalulekile zensimbi engagqwali engu-316L ukumelana kwayo okukhethekile nokugqwala, ikakhulukazi ezindaweni ezinezinga lokushisa eliphezulu. Lokhu kukwenza kube ukukhetha okuhle kakhulu ezinhlelweni zokusebenza lapho ukuchayeka emazingeni okushisa aphakeme kanye nezinto zamakhemikhali ezinolaka kukhathazeka. Ikhono lezinto ezibonakalayo lokumelana nezimo ezinzima kangaka ngaphandle kokuphazamisa ubuqotho bayo besakhiwo kuwubufakazi bokusebenza kwayo okuphezulu.
Ngaphezu kwalokho, insimbi engagqwali engu-316L ibhekwa kakhulu ngenxa ye-biocompatibility yayo, okwenza kube ukukhetha okuhle kwezimila zezokwelapha, ubucwebe bomzimba, nezinye izinhlelo zokusebenza lapho ukuthintana nomzimba womuntu kungenakugwema. Okuqukethwe kwekhabhoni ephansi kwento kanye nokwengezwa kwe-molybdenum kunomthelela ekuphikiseni kwayo ukuzwela, kunciphisa ubungozi bokungezwani nokungezwani nomzimba kubantu abangezwani nezinsimbi ezithile. Lesi sici se-biocompatibility siphinde sigcizelele ukuguquguquka nokuphepha kwe-316L yensimbi engagqwali ekusetshenzisweni okuhlukahlukene kwabathengi nezokwelapha.
Ngaphezu kokumelana nokugqwala kanye nokuvumelana kwayo ne-biocompatibility, insimbi engagqwali engu-316L ikhombisa ukuqina nokuqina okukhethekile. Lezi zakhiwo ziyenza ifanele uhla olubanzi lwemikhiqizo yezimboni nezabathengi, okuhlanganisa amathuluzi okuhlinza, okokusebenza olwandle, imishini yokucubungula ukudla, nezingxenye zezakhiwo. Ikhono lezinto ezibonakalayo lokumelana nezingcindezi zemishini, umthelela, nezimo zemvelo ezinokhahlo ligcizelela ukwethembeka kwayo nokuphila isikhathi eside ekusetshenzisweni okudingayo.
Uma kuziwa ekusetshenzisweni komkhiqizo, ukusebenza kwe-316L yensimbi engagqwali kuyaphawuleka ikakhulukazi ezindaweni ezinezinga lokushisa eliphezulu lapho ukumelana nokugqwala kubaluleke kakhulu. Amandla ayo okugcina ubuqotho besakhiwo nokumelana ne-oxidation emazingeni okushisa aphakeme ayenza ibe inketho ekahle yezishintshi zokushisa, amasistimu e-exhaust, izingxenye zesithando somlilo, nezinye izinto zokusebenza zezimboni ezisebenza ngaphansi kwezimo ezishisa kakhulu zokushisa.
Kafushane, insimbi engagqwali engu-316L iwumsebenzi ohlinzeka ngenhlanganisela eyingqayizivele yokumelana nokugqwala kwezinga lokushisa eliphezulu, i-biocompatibility, kanye nokuqina. Okuqukethwe kwayo kwekhabhoni ephansi, ukungezwa kwe-molybdenum, kanye nokwakheka kwayo yonke ingxubevange kunomthelela ekusebenzeni kwayo okukhethekile ezinhlelweni ezihlukene. Noma ngabe isemikhakheni yezokwelapha, yezimboni, noma yabathengi, i-316L insimbi engagqwali iyaqhubeka nokuba yinto ekhethwayo yemikhiqizo edinga ukwethembeka, ukuphila isikhathi eside, nokuphepha.
