Uma ukhetha insimbi engagqwali okumele ibekezelele izindawo ezibolayo, izinsimbi ezingenasici ze-austenitic zivame ukusetshenziswa.Njengoba inezakhiwo ezinhle kakhulu zemishini, amanani aphezulu e-nickel ne-chromium ezinsimbi ezingenasici ze-austenitic nazo zinikeza ukumelana nokugqwala okuvelele.Ukwengeza, izinsimbi eziningi ezingenasici ze-austenitic ziyashisela futhi ziyakheka.Amabanga amabili avame ukusetshenziswa kakhulu ensimbi engagqwali ye-austenitic amabanga 304 no-316. Ukukusiza ukuthi unqume ukuthi yiliphi ibanga elilungele iphrojekthi yakho, le bhulogi izohlola umehluko phakathi kuka-304 no-316 wensimbi engagqwali.
304 Insimbi Engagqwali
I-Grade 304 insimbi engagqwali ngokuvamile ithathwa njengensimbi engagqwali ye-austenitic evamile.Inokuqukethwe okuphezulu kwe-nickel okuvamise ukuba phakathi kwamaphesenti angu-8 no-10.5 ngesisindo kanye nenani eliphezulu le-chromium cishe kumaphesenti angu-18 kuya kwangu-20 ngesisindo.Ezinye izakhi ezinkulu ze-alloying zihlanganisa i-manganese, i-silicon, ne-carbon.Ingxenye yamakhemikhali esele ngokuyinhloko iyinsimbi.
Amanani aphezulu e-chromium ne-nickel anikeza insimbi engagqwali engu-304 ukumelana nokugqwala okuhle kakhulu.Izicelo ezijwayelekile ze-304 insimbi engagqwali zifaka:
- Imishini efana neziqandisi kanye nemishini yokugeza izitsha
- Imishini yokucubungula ukudla kwezohwebo
- Ama-Fasteners
- Ukubhobhoza
- Izishintshi zokushisa
- Izakhiwo ezisezindaweni ezingalimaza i-carbon steel ejwayelekile.
316 Insimbi Engagqwali
Ngokufanayo ne-304, i-Grade 316 yensimbi engagqwali inenani eliphezulu le-chromium ne-nickel.316 futhi iqukethe i-silicon, i-manganese, nekhabhoni, iningi lokwakheka kuyinsimbi.Umehluko omkhulu phakathi kwe-304 kanye ne-316 yensimbi engagqwali ukwakheka kwamakhemikhali, ne-316 equkethe inani elibalulekile le-molybdenum;ngokuvamile amaphesenti angu-2 kuya kwangu-3 ngesisindo uma kuqhathaniswa namanani okulandelela kuphela atholakala ku-304. Okuqukethwe okuphezulu kwe-molybdenum kuholela ebangeni lama-316 elinokumelana nokugqwala okwandisiwe.
Insimbi engagqwali engu-316 ivame ukubhekwa njengenye yezinketho ezifanele kakhulu lapho kukhethwa insimbi engagqwali ye-austenitic ezosetshenziswa olwandle.Ezinye izinhlelo zokusebenza ezijwayelekile ze-316 insimbi engagqwali zifaka:
- Imishini yokucubungula amakhemikhali neyokugcina.
- Imishini yokuhluza
- Imishini yezokwelapha
- Izindawo zasolwandle, ikakhulukazi lezo ezinama-chloride akhona
Yikuphi Okufanele Ukusebenzise: Ibanga 304 noma Ibanga 316?
Nazi ezinye izimo lapho i-304 insimbi engagqwali ingaba yisinqumo esingcono:
- Isicelo sidinga ukwakheka okuhle kakhulu.Okuqukethwe okuphezulu kwe-molybdenum ebangeni lama-316 kungaba nemiphumela emibi ekwakhekeni.
- Isicelo sinokukhathazeka ngezindleko.Ibanga lama-304 lithengeka kakhulu kuneBanga lama-316.
Nazi ezinye izimo lapho i-316 insimbi engagqwali ingaba yisinqumo esingcono:
- Imvelo ihlanganisa inani eliphezulu lezinto ezigqwalayo.
- Okubalulekile kuzofakwa ngaphansi kwamanzi noma kuvezwe emanzini njalo.
- Ezicelweni lapho kudingeka khona amandla amakhulu nobulukhuni.
