Iyo kabhoni yezvinyorwa uye kuomarara kwe440A-440B-440C yakawedzera kutevedzana kubva kuABC (A-0.75%, B-0.9%, C-1.2%). Iyo 440C yakakura kwazvo yakakwira-yekupedzisira isina tsvina simbi ine kuomarara kwe56-58 rc. Aya matatu manyoro ane hutano hwekurwisa, 440a ndiye akanakisa, uye 440c ndiye akaderera. Iyo 440C yakajairika. Kuumbwa kwemakemikari eMartensitic Stainless Simbi inoonekwa nekuwedzera kwezvinhu zvakaita seMolybdenum Sezvo chimiro cheTishu chenzvimbo ine muviri cubic chimiro, simba rinodonha zvakanyanya pakupisa kwakanyanya. Pazasi pe600 ° C, iyo yakakwira tembiricha simba ndiyo yepamusoro pakati pemhando dzese dzesimbi simbi, uye simba remukati rakanyanya kukwirisa. 440A ine zvakanakisa kudzima uye kuomesa zvivakwa uye kuomesa kwakanyanya. Iyo ine yakanyanya kuoma kupfuura 440b simbi uye 440c simbi. 440b inoshandiswa kucheka maturusi, kuyera zvishandiso, fani uye mavharuvhu. Iyo ine kuomarara kwakanyanya kupfuura 440a simbi uye yakakwirira kwazvo kupfuura 440c simbi. Iyo 440C ine kuomarara kwakanyanya kwese simbi isina simba uye kupisa-kupesana nesimbi uye kunoshandiswa kwemazwi uye fani. 440F igiredhi reSimbi rinovandudza zvivakwa zviri nyore
