IBanga lama-316 liyibanga elijwayelekile le-molybdenum, elesibili ngokubaluleka kuya ku-304 phakathi kwezinsimbi ezingenasici ze-austenitic.I-molybdenum inika izakhiwo ezingcono kakhulu ezingama-316 ezimelana nokugqwala kune-Grade 304, ikakhulukazi ukumelana nokugqwala nokugqwala kwemigodi ezindaweni ze-chloride.
Insimbi Engagqwali – Ibanga 316L – Izakhiwo, Ukwenziwa Nezicelo (UNS S31603)
IBanga 316L, inguqulo yekhabhoni ephansi engu-316 futhi ivikelekile ekuzwelweni (imvula ye-grain boundary carbide).Ngakho-ke isetshenziswa kakhulu ku-gauge esindayo izingxenye ezishiselwe (ngaphezu kuka-6mm).Ngokuvamile awukho umehluko wentengo oncomekayo phakathi kuka-316 no-316L wensimbi engagqwali.
Isakhiwo se-austenitic sinikeza lawa mabanga ukuqina okuhle kakhulu, ngisho naphansi kwamazinga okushisa e-cryogenic.
Uma kuqhathaniswa nezinsimbi ezingenasici ze-chromium-nickel austenitic, insimbi engagqwali engu-316L inikeza ukukhasa okuphezulu, ingcindezi ekuqhumeni namandla aqinile emazingeni okushisa aphakeme.
Izakhiwo Eziyinhloko
Insimbi Engagqwali – Ibanga 316L – Izakhiwo, Ukwenziwa Nezicelo (UNS S31603)
Lezi zakhiwo zicaciswe emikhiqizweni egoqeke isicaba (ipuleti, ishidi, nekhoyili) ku-ASTM A240/A240M.Izakhiwo ezifanayo kodwa ezingafani ngempela zicaciswe kweminye imikhiqizo efana nepayipi nebha ngokucaciswa kwazo.
