317 Insimbi Engagqwali
I-Stainless Steel 317 iyi-molybdenum-equkethe i-austenitic stainless steel enikeza ukumelana nokugqwala okuthuthukisiwe uma kuqhathaniswa namabanga avamile angu-304 nangu-316. Le alloy yaziswa kakhulu ngokusebenza kwayo okuphezulu ezindaweni ezinolaka, okuyenza ibe yinketho ekhethwayo ezinhlelweni ezihlukene zezimboni lapho ukumelana nokugqwala kubaluleke kakhulu.
Enye yezinzuzo ezibalulekile ze-Stainless Steel 317 ukumelana kwayo nokugqwala okuvelele. Isebenza kahle kakhulu ezinhlobonhlobo zemithombo yezindaba ebolayo, okuhlanganisa i-sulfuric acid, i-acetic acid, namanye ama-organic acid. Ukumelana kwayo ne-chloride{3}}okubangelwa ukugqwala kuyenza ifanelekele ukusetshenziswa ezindaweni zasolwandle, izimboni zokucubungula amakhemikhali, nengqalasizinda yasogwini. Ingxubevange iphinda ibonise ukumelana okuhle ne-oxidation emazingeni okushisa aphakeme, kufika cishe ku-870℃(1600℃F), okuyenza isebenziseke{7}}ezinhlelweni zokushisa eziphakeme njengezishintshisi zokushisa nezingxenye zesithando somlilo.

Isici
Okuqukethwe kwe-molybdenum ephezulu kuyinikeza ukumelana okukhethekile nokugqwala kwe-pitting kanye ne-crevice.317 insimbi engagqwali ibonisa ukusebenza okuvelele ekunciphiseni imidiya efana ne-sulfuric ne-phosphoric acid, enokumelana nokugqwala kwe-chloride ephakeme kakhulu uma kuqhathaniswa no-316. Inikeza ukusebenza kahle nokushibilika kahle, futhi ihlala ingelona isixazululo{}2}se-3}i-edic{2} isimo.
Izinhlelo zokusebenza
Izisetshenziswa Zekhemikhali Ezibalulekile:I-asidi eqinile (i-sulfuric/phosphoric acid) ama-reactors, amasistimu wokushibilika
I-Severe Marine Corrosion:Amashethi ekhebula angaphansi kwamanzi, izingxenye eziyinhloko zesitshalo sokususa usawoti emanzini
Amandla Nokuvikelwa Kwemvelo:I-flue gas scrubbers, i-waste incinerator linings
Izinkambu ezikhethekile:Imishini yokukhiqiza imfucuza, imikhumbi yokunqanda imfucuza yenuzi
Amashadi ashisayo: 317 insimbi engagqwali, China 317 abakhiqizi bensimbi engagqwali, abahlinzeki, imboni
