Ke tšepe e sa hloekang ea austenitic e nang le palo e phahameng ea chromium, nickel le element ea molybdenum e fanang ka bokhoni bo botle ba ho hanyetsa kutu.E na le khanyetso e phahameng ea litlamorao tsa lik'hemik'hale tse tsoang ho li-acid tse fapaneng.Alloy 317L e na le khabone e tlase e lumellang ho hanyetsa ho bola ha intergranular.E na le matla a phahameng a ho tsitsa ha mocheso o phahameng.E ka cheseha ka mekhoa eohle e tloaelehileng ea welding 'me e bonolo ho e sebelisa ka mechini e tloaelehileng. - Lintlha tsa maiketsetso
Tsena li sebelisoa ka mokhoa o chesang ho sebelisoa mekhoa eohle e tloaelehileng ea ho sebetsa e chesang.E halefile ka mocheso pakeng tsa 1149 ho ea ho 1260 ° C. Mocheso o lokela ho bolokoa ka tlase ho 927 ° C. Ts'ebetso ea ho thibela mosebetsi ka mor'a mosebetsi e susumetsoa ho eona ho boloka litšobotsi tse phahameng tsa ho hanyetsa kutu.Ho feta moo, ts'ebetso ena e etsoa ho fokotsa khatello ea kelello ka hare.Li-tubes tsa SS li huloa habonolo ka ts'ebetso e batang ea ho sebetsa.Phekolo ea mocheso e ke ke ea ama sebopeho, leha ho le joalo, ts'ebetso e batang ea ho sebetsa e lateloa ho fumana meaho e thata.
Tharollo ea annealing e etsoa ka mocheso o pakeng tsa 1010- 1121 degree C 'me e lateloe ke ho pholile.E tlas'a ts'ebetso ea ho qetela ea indasteri ho fumana litekanyo tse nepahetseng le ho qeta holimo. - Tsamaiso ea boleng
Sehlopha sohle sa rona se nchafalitsoe ho ts'ehetsa boitlamo ba boleng.Matla a rona a mantlha ke sehlopha se ikemiselitseng le se khothaletsoang.Re ikemiselitse ho fana ka lihlahisoa le litšebeletso tsa boleng bo holimo ho bareki.Kaha re barekisi ba lefats'e, re lekanya lihlahisoa tsa rona ka litekanyetso tse lumelletsoeng ke machabeng ho netefatsa boleng ba lihlahisoa.Teko ea boima, tlhahlobo ea conductivity ea mocheso, tlhahlobo ea ho lutla, tlhahlobo ea thepa e ntle, tlhahlobo ea kutu ea intergranular, le liteko tsa mochini, tse fanoeng litekong, li etsoa ke rona mohatong oa pele.
Tlhahlobo ea ho qetela e etsoa ke ba boholong ba mekhatlo ea boraro.Ho feta moo, liteko tsa bobeli ke teko e senyang, teko ea khatello, teko ea khatello ea maikutlo le tse ling tse ngata.
