Yini Eyenza I-304 vs 316 Idume Kangaka?
Amazinga aphezulu e-chromium ne-nickel atholakala ku-304 kanye ne-316 yensimbi engagqwali ahlinzeka ngokumelana okuqinile nokushisa, ukuhuzuka, nokugqwala. Akukhona nje ukuthi baziwa ngokumelana nokugqwala, baziwa nangokubukeka kwabo okuhlanzekile kanye nokuhlanzeka okuphelele.
Zombili izinhlobo zensimbi engagqwali zivela ezimbonini ezibanzi.Njengebanga elivame kakhulu lensimbi engagqwali, i-304 ibhekwa njengejwayelekile "18/8" engenasici. Insimbi engagqwali engu-304 isetshenziswa kakhulu ngoba ihlala isikhathi eside futhi kulula ukwenza izinhlobo ezahlukene njengeshidi lensimbi engagqwali, ipuleti lensimbi engagqwali, ibha yensimbi engagqwali, kanye neshubhu lensimbi engagqwali. Ukumelana kwensimbi engu-316 kumakhemikhali nasezindaweni zasolwandle kukwenza kube ukukhetha okudumile phakathi kwabakhiqizi.
Ahlukaniswa Kanjani?
Amakilasi amahlanu ensimbi engagqwali ahlelwa ngokusekelwe ekwakhiweni kwawo okucwebezelayo (indlela ama-athomu awo ahlelwe ngayo). Kulawa makilasi amahlanu, ama-304 kanye nama-316 ensimbi engagqwali asekilasini le-austenitic grade. Isakhiwo se-austenitic grade stainless steels siwenza angabi-magnetic futhi avimbele ukuthi aqine ngokwelashwa okushisa.

Ezokwelapha: amathreyi, amathuluzi okuhlinza.
2. Izakhiwo ze-316 Stainless Steel
316 iqukethe izinto eziningi ezifanayo zamakhemikhali nezomshini njenge-304 insimbi engagqwali. Ngeso lenyama, izinsimbi ezimbili zibukeka ngokufanayo. Kodwa-ke, ukwakheka kwamakhemikhali kwe-316, okwakhiwe nge-chromium engu-16%, i-nickel engu-10%, ne-2% ye-molybdenum, umehluko omkhulu phakathi kuka-304 no-316 wensimbi engagqwali.

Izicelo ze-316 Stainless Steel
Ukwengezwa kwe-Molybdenum ku-316 kuyenza imelane nokugqwala kakhulu kunama-alloys afanayo. Ngenxa yokumelana kwayo okuphakeme nokugqwala, i-316 ingenye yezinsimbi eziyisisekelo endaweni yasolwandle. I-316 insimbi engagqwali iphinde isetshenziswe ezibhedlela ngenxa yokuqina nokuhlanzeka kwayo.
Ukuphatha amanzi: ama-boilers, ama-heaters amanzi
Izingxenye zasolwandle- izinsimbi zesikebhe, intambo yocingo, izitebhisi zesikebhe

304 vs 316 Insimbi Engagqwali: Ukumelana Nokushisa
Ukumelana nokushisa kuyisici esibalulekile okufanele sicatshangelwe lapho uqhathanisa amamaki ahlukene ensimbi engagqwali. Ibanga lokuncibilika elingu-304 licishe libe ngu-50 kuya ku-100 degrees Fahrenheit ngaphezu kuka-316. Nakuba ububanzi bokuncibilika obungu-304 bungaphezu kuka-316, womabili anokumelana okuhle ne-oxidization kusevisi yesikhashana efika ku-870°C (1500℉) kanye nakusevisi eqhubekayo. ku-925°C (1697℉).
I-304 SS: Iphatha kahle ukushisa okuphezulu, kodwa ukusetshenziswa okuqhubekayo kokuthi 425-860 °C (797-1580 °F) kungase kubangele ukugqwala.
I-316 SS: Isebenza kahle kakhulu emazingeni okushisa angaphezu kuka-843 ℃ (1550 ℉) nangaphansi kuka-454 ℃ (850°F)
Umehluko Wamanani we-304 Stainless Steel vs 316
Yini eyenza i-316 ibize kakhulu kunensimbi engagqwali engama-304?
Ukwanda kokuqukethwe kwe-nickel kanye nokwengezwa kwe-molybdenum ku-316 kwenza kube kubi kakhulu kune-304. Ngokwesilinganiso, intengo ye-316 yensimbi engagqwali 40% ephakeme kunentengo ye-304 SS.
316 vs 304 Insimbi Engagqwali: Ikuphi Okungcono?
Uma kuqhathaniswa 304 insimbi engagqwali vs 316, bobabili banokuhle nokubi okufanele bacatshangelwe lapho benquma ukuthi iyiphi okumele bayisebenzisele izinhlelo zokusebenza ezahlukene. Isibonelo, insimbi engagqwali engu-316 imelana kakhulu nokungu-304 kusawoti nezinye izinto ezibolayo. Ngakho-ke, uma wenza umkhiqizo ovame ukubhekana nokuchayeka kumakhemikhali noma indawo yasolwandle, i-316 iyisinqumo esingcono.
Ngakolunye uhlangothi, uma wenza umkhiqizo ongadingi ukumelana nokugqwala okuqinile, i-304 iyinketho esebenzayo neyongayo. Kuzicelo eziningi, 304 kanye 316 empeleni ziyashintshana.
I-Jindalai Steel Group inguchwepheshe kanye nabaphakeli abahamba phambili ngensimbi nensimbi engagqwali. Thumela uphenyo lwakho futhi sizokujabulela ukubonisana nawe ngobuchwepheshe.
