Iyini i-SAF2205?

I-SAF2205 iyi-grade yakudala yensimbi engagqwali ephindwe kabili eyakhiwe yiSandvik, ekuqaleni okusho iSandvik Austenite Ferrite. Iyaziwa ngamandla ayo aphezulu kanye nokumelana okuhle kakhulu nokugqwala kwe-chloride stress, futhi ibhekwa njenge-idamu lamanziIzinto zokuthuthukisa kusukela ezinsimbini ezivamile ezingagqwali njenge-316L kuya ezinsimbini eziqinile ezingagqwali. Ukuhluka kwayo kusesimeni sayo sangaphakathi, esingaba yisigamu se-ferrite kanye nengxenye ye-austenite, okuhlanganisa izinzuzo zezakhiwo ezincane zombili.

Ukusebenza kwe-SAF2205 kungaqhathaniswa ngqo ne-benchmark 316L evame ukusetshenziswa kanje:

• Amandla:Cishe i-450 MPa, cishe kabili kune-316L, okuvumela ukujiya kodonga okunciphile.
• Ukumelana nokugqwala (inani le-PRE):≥35, iphakeme kakhulu kune-316L's 24. Inokumelana okunamandla kakhulu nokugqwala kwemigodi kanye nemifantu ezindaweni eziqukethe i-chloride (njengamanzi olwandle).
• Ukucindezeleka kokugqwala kokugqwala:Kuhle kakhulu. Ezindaweni eziqukethe i-chloride, i-316L ivame ukuqhekeka emazingeni okushisa angaphezu kuka-60°C, kanti i-SAF2205 inokumelana okuhle kakhulu.

I-SAF2205 inezinhlobo eziningana ezifanayo zamawele. Sicela uqaphele umehluko lapho uthenga:

• I-UNS S31803:Ibanga lokuqala.
• I-UNS S32205:Indinganiso yesimanje kakhulu futhi esetshenziswa kabanzi enokulawula okuqinile kokwakheka (ikakhulukazi i-nitrogen), kanye nokumelana nokugqwala okungcono kune-S31803 yezinga elidala.
• EN 1.4462:Ukuqokwa ngaphansi kwendinganiso ye-EU.

Ngokuhlanganisa"Amandla aphezulu + ukumelana nokugqwala", ivame ukusetshenziselwa ukufaka esikhundleni se-316L ukuze ibhekane nezimo zokusebenza ezinzima kakhulu:

• Imboni kaphethiloli namakhemikhali:ama-heat exchanger, amapayipi, imikhumbi yokucindezela, efanelekile kakhulu ezindaweni eziqukethe ama-ion e-chloride kanye ne-hydrogen sulfide.
• Ubunjiniyela bezolwandle:imishini yokukhipha usawoti emanzini olwandle, izingxenye zesakhiwo semikhumbi, ezimelana nokugqwala kwamanzi olwandle.
• Umkhakha wokwenza amaphepha kanye namakhemikhali:amabhodwe okupheka, imishini yokuhlikihla, amadivayisi e-PTA (purified terephthalic acid), njll.
• Izimo ezikhethekile:ingasetshenziswa futhi ukwenza iziphethu ezisebenza kahle kakhulu (-100 kuya ku-300℃ kuyasebenza) noma amathuluzi okwelapha amazinyo.
