Ucingo lwensimbi engagqwali

Insimbi engenasici iyinsimbi ephezulu ye-alloy engamelana nokugqwala emoyeni noma emithonjeni yezezimali eqinile. Insimbi engenasici inendawo enhle nokumelana okuhle kokugqwala. Akudingi ukwelashwa ngokwelashwa komhlaba njengokuthwebula amapuleti, kepha kunamandla okuthola impahla yemvelo yensimbi engenasici. Kuluhlobo lwensimbi esetshenziswa ezicini eziningi futhi luvame ukubizwa ngensimbi engenacala. Ukusebenza okumele kufaka i-13 chromium Steel, i-Chromium-Nickel Steel namanye ama-alloy aphezulu.

Ngokombono we-metallography, ngoba insimbi engenasici iqukethe i-chromium, ifilimu elincanyana kakhulu le-chromium lakhiwa ebusweni. Le filimu ihlukanisa umoya-mpilo ophazamisa insimbi futhi idlale indima engazweli ngokuphelele.
Ukuze ulondoloze ukumelana nokugqwala okungokompi kwensimbi engenasici, insimbi kufanele ibe ne-chromium engaphezu kwe-12%.
I-304 iyinsimbi evamile engenacala esetshenziswa kabanzi ukwenza imishini nezingxenye ezidinga ukusebenza okuhle okuhle (ukumelana nokugqwala kanye nensimbi engenasici). I-304 ilingana nezwe lami le-0Cr19NI9 (0Cr18NI9) insimbi engenacala. I-304 iqukethe i-19% chromium ne-9% nickel.
I-304 iyinsimbi esetshenziswa kakhulu yensimbi engenasici kanye nensimbi engasho lutho. Isetshenziswa emishini yokukhiqiza ukudla, imishini yamakhemikhali, amandla enuzi, njll.
