Uyini umehluko phakathi kuka-304 no-316 insimbi engagqwali?

Insimbi engagqwali iyinsimbi eyaziwayo futhi evame ukusetshenziswa kakhulu ekuthuthukisweni kwamashubhu ngenxa yokwakheka kwayo okuhlukahlukene kwamakhemikhali kanye nezakhiwo. Insimbi engagqwali itholakala ezinhlobonhlobo zamabanga, izinto zokwakha kanye nokucaciswa ukuhlangabezana nazo zonke izidingo zezimboni. I-SS 304 ingenye yezinsimbi ezingenazibuthe ne-austenitic ezisetshenziswa kakhulu, ezifanele ukwenziwa kwazo zonke izinhlobo zamapayipi. 304 insimbi engagqwali amashubhu kanye 316 insimbi engagqwali amashubhu atholakala ngezindlela ezihlukahlukene ezifana nekhono, ashiselwe kanye flange.

304 insimbi engagqwali kanye nokusetshenziswa kwayo
Thayipha insimbi engagqwali engu-304, enokuqukethwe kwe-chromium-nickel kanye nekhabhoni ephansi, iyona eguquguqukayo kakhulu futhi esetshenziswa kabanzi yezinsimbi ezingenasici ze-austenitic. Ama-alloys ayo wonke ama-alloys e-austenitic alloy ene-chromium engu-18% ne-nickel engu-8%.
I-Type 304 ifakazele ukuthi iyakwazi ukumelana ne-oxidation kanye nokubola futhi ihlala isikhathi eside.
Uhlobo lwe-304 insimbi engagqwali amashubhu isetshenziswa ekuvaleni kukagesi ukumelana nokugqwala, ekubunjweni nasekulungiseni izimoto, izembozo zamasondo, izinto zasekhishini, izinsimbi zamapayipi, amapayipi amaningi, insimbi engagqwali, amathangi okugcina, imikhumbi yokucindezela namapayipi.
316 insimbi engagqwali kanye nokusetshenziswa kwayo
Thayipha ishubhu yensimbi engagqwali engu-316 iyinsimbi engagqwali ye-chromium-nickel eyi-austenitic futhi imelana nokushisa enokumelana nokugqwala okuphakeme uma kuqhathaniswa nezinye izinsimbi ze-chromium-nickel lapho evezwe ezinhlotsheni eziningi zokubola kwamakhemikhali njengamanzi olwandle, izixazululo zikasawoti nokunye okunjalo.
Ishubhu yengxubevange yohlobo 316 SS iqukethe i-molybdenum, okuyenza imelane nokuhlaselwa kwamakhemikhali kunoHlobo lwama-304. Uhlobo 316 luqinile, kulula ukulenza, luhlanzeke, lushisele futhi luqede. Imelana kakhulu nezixazululo ze-sulfuric acid, ama-chlorides, ama-bromides, ama-iodide nama-fatty acids emazingeni okushisa aphezulu.
I-SS equkethe i-molybdenum iyadingeka ekukhiqizeni imithi ethile ukuze kugwenywe ukungcoliswa kwensimbi ngokweqile. Okubalulekile ukuthi ama-stainless steels angu-316 aqukethe i-molybdenum ayadingeka ekukhiqizeni imithi ethile ukuze kugwenywe ukungcoliswa kwensimbi ngokweqile.
