Yini eyenza i-304 vs 316 ithandwa kangaka?
Amazinga aphezulu we-chromium kanye ne-nickel etholakala ngo-304 kanti ama-stainless ensimbi athola ukumelana okuqinile kokushisa, abrasion kanye nokugqwala. Akukhona nje kuphela ukuthi bazaziwa ngokumelana kwabo nokugqwala, baziwa ngokubukeka kwabo okuhlanzekile nokuhlanzeka okuphelele.
Zombili lezi zinhlobo zensimbi engagqwali zivele zivele izimboni zemikhakha ezihlangeneyo. Insimbi engu-304 isetshenziswa kabanzi kusetshenziswa kabanzi ngoba ihlala isikhathi eside futhi kulula ukuyisebenzisa ngezindlela ezahlukahlukene ezifana nephepha lensimbi elingagqwali, ipuni lensimbi engagqwali, ibha yensimbi engagqwali Ukumelana kwensimbi 316 kumakhemikhali kanye nezindawo zasolwandle kwenza kube ukukhetha okuthandwa phakathi kwabakhiqizi.
Bahlukaniswa kanjani?
Amakilasi amahlanu wensimbi engenasici ahlelwe ngokusekelwe esakhiweni sawo se-crystalline (indlela ahlelwe ngayo ama-athomu awo). Emakilasini amahlanu, i-304 nensimbi engenacala zisekilasini lebanga le-auntenitic. Ukwakheka kwe-Autenitic Ibanga elingenacala kubenza babe ngamabuthe futhi abavimbele ekubeni bunzima ukwelashwa okushisa.

2. Izakhiwo zensimbi engama-316 engenasici
I-316 iqukethe izakhiwo eziningi ezifanayo zamakhemikhali nezemishini njengensimbi engama-304 engagqwali. Esweni elinqunu, lezi zinsimbi ezimbili zibukeka zinjalo. Kodwa-ke, ukwakheka kwamakhemikhali angama-316, okwenziwe nge-16% i-chromium, i-10% nickel, no-2% molybdenum, umehluko omkhulu phakathi kuka-304 no-316 insimbi engagqwali.

Izicelo zensimbi engagqwali
Ukungezwa kwe-molybdenum ngo-316 kwenza kube nokuqina ngokwengeziwe kunama-alloys afanayo. Ngenxa yokumelana kwayo okuphakeme kokugqwala, 316 kungenye yezinsimbi ezibunjiwe ezindaweni zasolwandle. Insimbi engama-316 isetshenziswe futhi ezibhedlela ngenxa yokuqina kwayo nokuhlanzeka.
Ukuphathwa kwamanzi: Ama-boilers, ama-heater amanzi

304 vs 316 Insimbi engenacala: Ukumelana nokushisa
Ukumelana nokushisa kuyinto ebalulekile okufanele uyicabangele uma uqhathanisa amamaki ahlukene wensimbi engenasici. Uhla lwe-304 lungacishe lube ngu-50 kuye ku-100 degrees Celsiet ngaphansi kwama-316. Yize uhla lokuncibilika olungu-304 luphezulu kwe-oxidization insizakalo ye-870 ° C (1500 ℉) naku-1697 ℉).
I-304 SS: Isingatha ukushisa okuphezulu kahle, kepha ukusetshenziswa okuqhubekayo ngo-425-860 ° C (797-1580 ° F) kungadala ukugqwala.
I-316 SS: Isebenza kahle emazingeni okushisa angenhla kwe-843 ℃ (1550 ℉) nangaphansi kwe-454 ℃ (850 ° F)
Umehluko wentengo wensimbi engama-304 engagqwali vs 316
Yini eyenza ibiza kakhulu kunensimbi engama-304 engagqwali?
Ukwanda kokuqukethwe kwe-nickel nokungezwa kwe-molybdenum ngo-316 kwenza kube biza kakhulu kune-304. Ngokwesilinganiso, intengo yensimbi engama-316 i-40% ephakeme kunentengo yama-304 ss.
316 vs 304 insimbi engagqwali: okungcono?
Uma uqhathanisa insimbi engama-304 engenasici Isibonelo, insimbi engagqwali engama-316 imelana kakhulu kune-304 kusawoti nakwamanye ama-corlives. Ngakho-ke, uma ukhiqiza umkhiqizo ovame ukubhekana nokuchayeka kumakhemikhali noma imvelo yasolwandle, 316 ukukhetha okungcono.
Ngakolunye uhlangothi, uma wenza umkhiqizo ongadingi ukumelana okuqinile kokugqwala, 304 uwukukhetha okusebenzayo futhi okungokomnotho. Ukuze uthole izinhlelo eziningi, 304 no-316 empeleni ziyakwazi ukuzishintsha.
I-Jindalai Steel Group iyingcweti futhi ehola umphakeli ngensimbi nensimbi engenacala. Thumela uphenyo lwakho futhi sizokujabulela ukukubona kahle.
