409 430 439 441 443 ndiro yesimbi isina tsvina
Tsanangudzo yekugadzira:
400 akatevedzana Stainless simbi ndeye alloy yesimbi, kabhoni uye chromium. Nekuti haina nickel,
isimbi inochengetedza nickel, inozivikanwawo sesimbi isina tsvina. 400 akatevedzana Stainless simbi ane zvakajairika
magineti maitiro nekuda kweiyo martensitic chimiro uye iron.
400 yakatevedzana Stainless simbi ine yakasimba kuramba kune yakanyanya tembiricha oxidation, uye yayo yemuviri uye michina
zvivakwa zvinowedzera kuvandudzwa zvichienzaniswa nekabhoni simbi. Mazhinji 400 akatevedzana masimbi asina tsvina anogona kupisa kupisa.

Application:
1. 409 Stainless simbi : 409L ine yakasimba tembiricha inopikisa, inogona kuwana yakakwirira-inoshanda injini uye
exhaust system, uye kuderedza kukora kweiyo exhaust system, iyo inogona kuderedza exhaust emissions.
409L ine mutengo wakaderera, yakanaka kuchinjika, goho repamusoro uye nyore kutsiva. Icho chigadzirwa chitsva chekuchengetedza zvakatipoteredza.
2. 430 simbi isina simbi: Yekushongedza chivako, zvikamu zvinopisa mafuta, midziyo yemumba, midziyo yemumba.
430F igiredhi resimbi rine mahara ekucheka zvivakwa zvakawedzerwa kune 430 simbi, iyo inonyanya kushandiswa kune otomatiki lathes, mabhaudhi uye nzungu.
3. 439 simbi isina simbi: Erevheta, mapanera ekushongedza anokwidza; zvivakwa zvekushongedza mapaneru, senge ekushongedza zvimiro zvikamu,
mapaipi ekugadzira; Automotive exhaust system zvikamu; washing machine tabhu yemukati
4. 441 simbi isina simbi: Exhaust manifold, pombi yekumberi, CONVERTER, nezvimwewo zvemotor exhaust system.
5. 443 simbi isina simbi: Simbi isina simbi 443 imhando yesimbi isina simbi. Inowanzo shandiswa kutsiva 304.
Kuramba kwayo ngura uye mashandiro ekugadzirisa haana simba kupfuura 304, asi mutengo wakaderera. Inoshandiswa zvakanyanya mu
midziyo yemagetsi, midziyo, midziyo yekicheni, maelevator, ovheni nemimwe minda.
