Heano mamwe mapoinzi akakosha ekuisa bhaa resimbi isina ngura re440C:
1. Musanganiswa: 440C stainless steel flat bar inonyanya kuumbwa ne chromium (16-18%), kabhoni (0.95-1.20%), uye zvimwe zvinhu zvakaita se manganese, silicon, uye molybdenum.
2. Kusapfeka: 440C stainless steel flat bar inozivikanwa nekudzivirira kwayo kupfeka, zvichiita kuti ikodzere kushandiswa nezvinhu zvinokwesha, maturusi ekucheka, mabheringi, uye zvinhu zvinodzivirira kupfeka.
3. Kuramba Kuora: Kunyangwe iri simbi isingasvibi ine kabhoni yakawanda, 440C inodzivirira ngura zvakanaka.
4. Kuomarara uye Simba: 440C stainless steel flat bar ine kuomarara kwakanaka uye simba rayo guru, ichipa kugara kwenguva refu uye kugara kwenguva refu mukushandiswa kwayo kwakaoma.
