440—Isixhobo sensimbi esisika amandla kunye nomxholo wekhabhoni ophakamileyo. Emva konyango olufanelekileyo lobushushu, amandla aphezulu esivuno anokufumaneka. Ubulukhuni bunokufikelela kuma-58HRC, aphakathi kwezona zintsimbi zinzima. Owona mzekelo uqhelekileyo wesicelo "zezincakuba". Zintathu iimodeli ezisetyenziswa ngokuxhaphakileyo: 440A, 440B, 440C, kunye no-440F (kululauhlobo lokuqhubekeka).
Umgaqo webhola engenasici:
Iibhola zentsimbi engenasici azinabungqina bumhlwa, kodwa akukho lula ukurusa. Umgaqo-siseko kukuba ngokudibanisa i-chromium, umaleko oxineneyo we-chromium oxide wenziwa kumphezulu wesinyithi, onokuthi uthintele ngokufanelekileyo unxibelelwano kwakhona phakathi kwesinyithi kunye nomoya, ukuze ioksijini esemoyeni ingangeni kwisinyithi. ibhola, ngaloo ndlela kuthintelwa Isiphumo iibhola zentsimbi umhlwa.
Imigangatho yeSizwe yase China (CNS), iMigangatho yoShishino yaseJapan (jis) kunye neAmerican Iron and Steel Institute (AISI) zisebenzisa amanani amathathu ukubonisa iintlobo ngeentlobo zentsimbi ezingenacici, nezicatshulwe kakhulu kolu shishino, apho uthotho lwama-200 luyi-chromium-nickel-manganese -based austenitic Yenziwe ngentsimbi eshayinayo, 300 uthotho chromium-nickel austenitic insimbi, 400 series chromium insimbi (eyaziwa ngokuba intsimbi), kubandakanya martensite kunye ferrite.
