Ngokuvumelana nokwakheka, ingahlukaniswa ngochungechunge lwe-Cr (uchungechunge lwama-400), uchungechunge lwe-Cr-Ni (uchungechunge lwama-300), i-Cr-Mn-Ni (uchungechunge lwama-200), insimbi engamelani nokushisa ye-chromium alloy (uchungechunge lwama-500) kanye nesistimu yokuqina kwemvula. (600 uchungechunge).
201: ukumelana nokugqwala okungekuhle, kusetshenziswa kabanzi njengendawo eshibhile yochungechunge lwama-300 eChina.
304: iyona esetshenziswa kakhulu.imikhiqizo efana: iziqukathi ezikwazi ukumelana nokugqwala, i-tableware,
ifenisha, izinsimbi, imishini yezokwelapha.
316: uhlobo lwensimbi lwesibili olusetshenziswa kakhulu lusetshenziswa kakhulu embonini yokudla, amawashi nobucwebe,
imboni yemithi kanye nemishini yokuhlinza.
430: Insimbi engagqwali yeFerritic, yokuhlobisa, isibonelo ezesekeli zemoto.Ukubumba okuhle, kodwa kumpofu
ukumelana nezinga lokushisa nokumelana nokugqwala.
