I-Saky Steel Masteensic Stainess Stainess luhlobo lwensimbi yeChromium egcina uMarganitititititititiciaticious kwiqondo lokushisa, ezona zinokuhlengahlengiswa ngunyango lobushushu (ukucima kunye nokucofa). Ngokubanzi, luhlobo lwentsimbi engenakukhuni. Emva kokucingisisa, ukuwatshata kunye nenkqubo yokuthiyisha, ubushushu bentsimbi engama-440 buye baphuculwa kakhulu kunaleyo bezinye izithambisi ezingenasiseko nebubushushu. Iqhelekile isetyenziselwa ukwenziwa kwemveliso, izixhobo zokusika, okanye izityalo zeplastiki ezifuna imithwalo ephezulu kwaye zinxibe ukungavisisani phantsi kweemeko zolwaphulo-mthetho. I-American Standard Grivery intsimbi engenasitali kubandakanya: 440A, 440B, 440C, 440f. Umxholo wekhabhoni we-440A, i-440b kunye ne-440c inyuke ngokulandelelana. I-440F (i-ASTM A582) luhlobo lwensimbi yokusika i-SITED kunye ne-S e-S engezelwe kwisiseko se-440c.

Ifana nentsimbi eqhelekileyo yentsimbi, i-Saky Steel's 440 'ye-Saky Steel Merite Steiness Staines ineempawu zokwenza lukhuni ngokucimeka, kwaye inokufumana uluhlu olubanzi lweepropathi zoomatshini. Ngokubanzi, i-440A isebenza nzima kakhulu kunye nobunzima obukhulu, kwaye ubunzima bayo buphezulu kune-440b kunye ne-440c. I-440B inelukhuni ephezulu kunye nobunzima kune-440A kunye ne-440c ye Izixhobo zokusika, izixhobo zokulinganisa, iibheringi kunye neevuni. I-440C inobuqili obuphezulu bazo zonke iintsimbi ezixhaphakileyo kunye nobushushu bezixhobo eziphezulu ezikumgangatho ophezulu zokusika, i-nozzles kunye nebheringi. I-440F yintsimbi enqunyulweyo yasimahla kwaye isetyenziswe ikakhulu kwii-lathes ezenzekelayo.
