Ukwenziwa kunye noNyango loBushushu
Ubuchule
Ngaba ujonge izixhobo zokuhlalutya iintsimbi zakho?
IBanga le-317 insimbi engenasici yomelele kunentsimbi ye-304.Kucetyiswa ukuba usebenzise i-chip breakers.Ukuqina kwale alloy kuya kuncitshiswa ukuba ukutya rhoqo kunye nezantya eziphantsi zisetyenziswa.
Ukuwelda
IBanga le-317 insimbi engenasici inokudityaniswa ngokusebenzisa ukudibanisa kunye neendlela zokumelana.Indlela ye-welding ye-Oxyacetylene ayikhethwanga kule alloy.I-AWS E/ER317 okanye i-317L yentsimbi yokuzalisa ingasetyenziselwa ukufumana iziphumo ezilungileyo.
Ukusebenza okushushu
IBanga le-317 insimbi engenasici inokushushu isetyenzwe ngokusebenzisa zonke iinkqubo eziqhelekileyo zokusebenza ezishushu.Ifudunyezwa kwi-1149-1260 ° C (2100-2300 ° F).Akufunekanga itshiswe ngaphantsi kwe-927°C (1700°F).Ukuvalwa komsebenzi wasemva komsebenzi kunokwenziwa ukuze kugcinwe ipropathi yokuxhathisa umhlwa.
Ukusebenza Okubandayo
Ukunyathela, ukucheba, ukuzoba, kunye nesihloko kunokwenziwa ngempumelelo.I-post-work annealing yenziwa ukwenzela ukunciphisa uxinzelelo lwangaphakathi.
