Ingabe i-409 insimbi engagqwali kazibuthe?

Insimbi engagqwali iyinto edumile esetshenziswa ezimbonini ezahlukahlukene ngenxa yokumelana nokugqwala nokuqina kwayo. Phakathi kwezinhlobo eziningi zensimbi engagqwali, i-409 iyibanga elithile elivame ukusetshenziswa ezinhlelweni lapho ukuchayeka endaweni ebolayo kulindeleke. Kodwa-ke, umbuzo ovamile ophakamayo uma kucutshungulwa le nto ukuthi ngabe insimbi engagqwali engu-409 iyizibuthe noma cha.

 

Ukwakheka kwamakhemikhali kwensimbi engagqwali engu-409

I-409 insimbi engagqwali iyingxubevange ye-chromium-nickel eyingxenye yomndeni we-ferritic wezinsimbi ezingenasici. Iqukethe phakathi kuka-10.5% no-11.7% we-chromium, okuyenza ikwazi ukumelana nokugqwala, kanye nenani elincane le-nickel, ngokuvamile elilinganiselwa ku-0.5%. Kodwa-ke, umehluko oyinhloko phakathi kwama-409 namanye ama-alloys ensimbi engagqwali okuqukethwe kwayo kwekhabhoni, ephakeme kunamanye amamaki ensimbi engagqwali.

 

Izakhiwo Zezibuthe ze-409 Stainless Steel

Okuqukethwe kwekhabhoni ku-409 insimbi engagqwali kudlala indima ebalulekile ekunqumeni izici zayo kazibuthe. Njengoba inokuqukethwe kwekhabhoni ephezulu, ithambekele kakhulu ekwenzeni i-martensite, isigaba se-ferromagnetic sama-alloys e-iron-carbon. Lokhu kwakheka kwe-martensite kwenza insimbi engagqwali engu-409 ingabi namandla kazibuthe.

Manje, igama elithi "uzibuthe obuthakathaka" libalulekile lapha. Nakuba insimbi engagqwali engu-409 ingenamandla kazibuthe njengamanye ama-alloys ensimbi, isabonisa izinga elithile likazibuthe. Lokhu kungenxa yokuba khona kwezakhi ze-ferromagnetic njenge-iron ne-carbon ekwakhekeni kwayo.

 

Ukusetshenziswa okusebenzayo kwensimbi engagqwali engu-409

Izakhiwo kazibuthe ze-409 insimbi engagqwali zingase zibe nomthelela ekusetshenzisweni kwayo kwezinye izindawo ezithile. Isibonelo, emishinini kagesi noma emishinini yezokwelapha edinga ukugwema ukuphazamiseka kwakazibuthe, ukusebenzisa i-409 insimbi engagqwali kungase kungabi inketho engcono kakhulu. Kweminye imikhakha, njengokwakha nokukhiqiza izimoto, izici zayo kazibuthe zingase zingabi nomthelela omkhulu.

 

Isiphetho

Kafushane, insimbi engagqwali engu-409 inozibuthe ebuthaka ngenxa yokuqukethwe kwayo kwekhabhoni kanye nokwakheka kwe-martensite. Nakuba ingeyona ikazibuthe enamandla njengamanye ama-alloys ensimbi, isabonisa izinga elithile lamagnetism. Lokhu kufanele kucatshangelwe lapho kucatshangelwa ukusetshenziswa kwayo ezinhlelweni lapho i-magnetism ingase ibe yinto ekhathazayo.
