SUS410 / SUS420J2 / SUS430 mikanda yazitsulo zosapanga dzimbiri Kuyerekeza：
SUS410: Martensite imayimira kalasi yazitsulo, ndi mphamvu yayikulu komanso kuuma kwambiri (maginito); kukana kwakanthawi kwa dzimbiri, kosayenera kugwiritsidwa ntchito m'malo owononga kwambiri; otsika C okhutira, workability wabwino, ndi padziko akhoza kuumitsidwa ndi kutentha mankhwala.
SUS420J2: Martensite imayimira kalasi yazitsulo, ndi mphamvu yayikulu komanso kuuma kwambiri (maginito); kusagwirizana bwino ndi dzimbiri, kukonza bwino komanso kusasintha, komanso kukana kwabwino; Ikhoza kuthandizidwa ndi kutentha kukonza makina. Amagwiritsidwa ntchito kwambiri pokonza mipeni, ma nozzles, mavavu, olamulira, ndi tableware.
SUS430: Kutentha kotsika kotsika, kuumba bwino komanso kukana makutidwe ndi okosijeni. Zoyenera zida zosagwira kutentha, zotentha, zida zapanyumba, kalasi ya 2 tableware, masinki okhitchini. Mtengo wotsika, kugwira ntchito bwino ndi njira yabwino m'malo mwa SUS304; dzimbiri kukana, wamba osakhala kutentha mankhwala olimba ferritic zosapanga dzimbiri.

Mfundo za mpira zosapanga dzimbiri:
Mikanda yazitsulo zosapanga dzimbiri siyopanda dzimbiri, koma zimakhala zosavuta kuchita dzimbiri. Mfundo yake ndiyakuti pakuwonjezera kwa chromium, dothi lolimba la chromium oxide limapangidwa pamwamba pazitsulo, zomwe zimatha kuletsa kuyanjananso pakati pazitsulo ndi mlengalenga, kuti mpweya mumlengalenga usalowe muzitsulo mpira, potero poteteza zotsatira za mikanda yazitsulo.
China National Standards (CNS), Japan Industrial Standards (JIS) ndi American Iron and Steel Institute (AISI) imagwiritsa ntchito manambala atatu posonyeza ma steel osapanga dzimbiri, omwe amatchulidwapo kwambiri pamakampaniwa, pomwe mndandanda 200wu ndi chromium-nickel-manganese -based austenitic zosapanga dzimbiri, 300 mndandanda ndi chromium-faifi tambala austenitic zosapanga dzimbiri, 400 mndandanda chromium zosapanga dzimbiri (imadziwika monga chitsulo zosapanga dzimbiri), kuphatikizapo martensite ndi ferrite.
