Xa ukhetha intsimbi engenasistainless ekufuneka inyamezele indawo ezonakalisayo, i-austenitic stainless steels idla ngokusetyenziswa.Ukufumana iipropathi ezigqwesileyo zoomatshini, izixa eziphezulu zenickel kunye nechromium kwiintsimbi ze-austenitic ezingenasici nazo zibonelela ngokumelana nokugqwesa okugqwesileyo.Ukongeza, iintsimbi ezininzi ze-austenitic ezingenasici ziyakwazi ukuwelda kwaye zenziwe.Amanqaku amabini asetyenziswa ngokuqhelekileyo e-austenitic steel stainless amabakala 304 kunye ne-316. Ukukunceda ukuba ubone ukuba yiyiphi ibakala efanelekileyo kwiprojekthi yakho, le bhulogi iya kuhlola umahluko phakathi kwe-304 kunye ne-316 yensimbi engenasici.
304 Intsimbi engatyiwa
IBanga le-304 insimbi engenasici ngokuqhelekileyo ithathwa njengeyona nto ixhaphakileyo ye-austenitic stainless steel.Iqulethe umxholo ophezulu we-nickel ophakathi kwe-8 kunye ne-10.5 yepesenti ngobunzima kunye nexabiso eliphezulu le-chromium malunga ne-18 ukuya kwi-20 ekhulwini ubunzima.Ezinye izinto eziphambili zokudibanisa ziquka i-manganese, i-silicon, kunye nekhabhoni.Intsalela yokwakheka kweekhemikhali ikakhulu yintsimbi.
Izixa eziphezulu zechromium kunye ne-nickel zinika i-304 yentsimbi egqwesileyo egqwesileyo yokuxhathisa umhlwa.Ukusetyenziswa okuqhelekileyo kwe-304 yensimbi engenasici kubandakanya:
- Izixhobo ezifana neefriji kunye nezixhobo zokuhlamba izitya
- Izixhobo zokuthengisa ukutya
- Izibophelelo
- Imibhobho
- Izitshintshi zobushushu
- Ulwakhiwo olukwiindawo ezinokuthi zonakalise intsimbi yekhabhoni eqhelekileyo.
316 Intsimbi engatyiwa
Ngokufana ne-304, iBakala 316 insimbi engenasici inexabiso eliphezulu le-chromium kunye ne-nickel.I-316 ikwaqulethe i-silicon, i-manganese, kunye nekhabhoni, kunye nobuninzi bokwakheka kwentsimbi.Umehluko omkhulu phakathi kwe-304 kunye ne-316 yensimbi engenasici kukubunjwa kweekhemikhali, kunye ne-316 equkethe inani elikhulu le-molybdenum;ngokwesiqhelo isi-2 ukuya kwisi-3 sepesenti ngobunzima xa kuthelekiswa nezixa zomkhondo ezifumaneka kuma-304 kuphela.
I-316 insimbi engenasici ihlala ithathwa njengenye yezona zikhetho ezifanelekileyo xa ukhetha i-austenitic stainless steel kwizicelo zaselwandle.Ezinye izicelo eziqhelekileyo ze-316 insimbi engenasici ziquka:
- Ukusetyenzwa kweekhemikhali kunye nezixhobo zokugcina.
- Izixhobo zokucoca
- Izixhobo zonyango
- Iindawo zaselwandle, ngakumbi ezo zinekloridi ezikhoyo
Yeyiphi ofanele ukuyisebenzise: iBakala 304 okanye iBakala 316?
Nazi ezinye iimeko apho i-304 insimbi engenasici inokuba lolona khetho lungcono:
- Isicelo sifuna ukwakheka okugqwesileyo.Umxholo ophezulu we-molybdenum kwiBanga lama-316 unokuba nemiphumo emibi ekubumbeni.
- Isicelo sinenkxalabo yeendleko.IBanga lama-304 lifikeleleka ngakumbi kuneBanga lama-316.
Nazi ezinye iimeko apho i-316 insimbi engenasici inokuba lolona khetho lungcono:
- Imo engqongileyo ibandakanya isixa esikhulu sezinto ezonakalisayo.
- Izinto eziphathekayo ziya kufakwa ngaphantsi kwamanzi okanye zibonakaliswe emanzini ngokuqhubekayo.
- Kwizicelo apho kufuneka amandla amakhulu kunye nobunzima.
