Sky Steel Martensitic Stainless Simbi isimbi yeChromium Stainless Simbi panzvimbo yemukati tembiricha, ine zvivakwa zvinogona kugadziridzwa nekushambadzira kurapwa (kudzima nekutsamwa). Kazhinji, ndirwo rudzi rwesimbi yakaoma isina tsvina. Pashure pekupedzisa, kupaza uye kusimbisa maitiro, kuomarara kweiyo 440 simbi isina kuvandudzwa kwazvo kupfuura iyo yeimwe isina simba uye kupisa inodziya. Izvo zvinowanzoshandiswa mukugadzirwa kwekubereka, kucheka zvishandiso, kana mapurasitiki ekuumba izvo zvinoda zvakakwirira zvemitoro uye kupfeka kuramba mumamiriro ezvinhu akaora. American Standard 440 Series Simbi Stainless Steel inosanganisira: 440a, 440b, 440c, 440F. Iyo kabhoni yezvinyorwa zve440a, 440b uye 440c yakawedzera zvinotevera. 440F (ASTM A582) ndiyo mhando yeiyo yemahara yekucheka simbi ine zvirimo yakawedzerwa pane iyo nheyo ye440c.

Zvakafanana neyakajairwa Alloy Simbi, Sky Steel's 440 Steel Martensite Stainless Simbi ine maitiro ekupisa, uye anogona kuwana huwandu hwakawanda hwezvivakwa kuburikidza nekuita kwakasiyana kupisa. Muzhinji, 440a ine chekuita zvakanyanya nekuomesa musoro uye kuomesa kwakakwirira, uye kuoma kwayo kwakakwirira kupfuura iyo ye440b uye 440c. 440b ine kuomarara kwakanyanya uye kuomarara kupfuura 440a uye 440c ye Kucheka maturusi, kuyera zvishandiso, fani uye mavharuvhu. Iyo 440C ine kuomesesa kwepamusoro kwese simbi isina simba uye kupisa kunodzivirira simbi yemhando yepamusoro yekucheka maturusi, mazwi uye fani. 440F isimbi yemahara-yekucheka uye inonyanya kushandiswa mune otomatiki lathes.
