UMAHLUKO PHAKATHI kuka-304 KUNYE NE-316 ENZINDLU

Xa ukhetha iyenziwe ngentsimbi eshayinayoekufuneka inyamezele iindawo ezinobungozi,iintsimbi ze-austenitic ezingenasicizisetyenziswa ngokuqhelekileyo. 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 stainless steel ngamabakala304kwaye316. Ukukunceda ukuba uqonde ukuba leliphi ibakala elilungele iprojekthi yakho, le bhlog iya kuhlola umahluko phakathi kwe-304 kunye ne-316 yensimbi engenasici.

304 Intsimbi engatyiwa

IBanga lama-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.
