Saky simbi Martensitic Stainless simbi imhando yechromium Stainless simbi inochengetedza martensitic microstructure pane tembiricha yekamuri, ine zvimiro zvinogona kugadziriswa nekupisa kurapwa (kudzima uye kupisa). Kazhinji kutaura, imhando yesimbi yakaoma isina tsvina. Mushure mekudzima, kudziya uye kupinza, Kuomarara kwe440 simbi isina tsvina kwakagadziridzwa zvakanyanya kupfuura kune mamwe masimbi asina tsvina uye anodzivirira kupisa. Inowanzoshandiswa mukugadzirwa kwekutakura, kucheka maturusi, kana molds epurasitiki inoda mitoro yakakura uye kupfeka kusagadzikana pasi pemamiriro ekuora. American mwero 440 akatevedzana Stainless simbi inosanganisira: 440A, 440B, 440C, 440F. Iyo kabhoni yemukati ye440A, 440B uye 440C yakawedzera zvakateerana. 440F (ASTM A582) imhando yesimbi yemahara yekucheka ine S yemukati yakawedzerwa pahwaro hwe440C.

Zvakafanana neyakajairwa alloy simbi, Saky simbi's 440 yakatevedzana Martensite Stainless simbi ine hunhu hwekuomesa kuburikidza nekudzima, uye inogona kuwana huwandu hwakasiyana hwemakanika zvivakwa kuburikidza nekupisa kwakasiyana kurapwa. Kazhinji, 440A ine kuita kwakanakisa kuomesa uye kuomarara kwepamusoro, uye kuomarara kwayo kwakakwira kupfuura iyo ye440B uye 440C. 440B ine kuoma kwepamusoro uye kuoma kupfuura 440A uye 440C ye midziyo yekucheka, maturusi ekuyeresa, mabearings nemavharuvhu. Iyo 440C ine yakanyanya kuoma kwese simbi isina tsvina uye inodzivirira kupisa simbi yemhando yepamusoro yekucheka maturusi, nozzles uye mabhengi. 440F isimbi yemahara-yekucheka uye inonyanya kushandiswa mune otomatiki lathes.
