65Mn intsimbi eshushu eqengqelekayo imivalo engqukuva

Intsimbi ye-65Mn yi-GB yaseTshayina esemgangathweni yentsimbi yasentwasahlobo, iManganese (Mn) iphucula ukuqina, ngoko ke amandla, ukuqina, ukuqina kunye nokuqina kuphezulu kunoko kwentsimbi ye-65 #, kodwa inovakalelo olugqithisileyo kunye nokucaphuka komsindo. Ukucinywa kwamanzi kudla ngokwenza iintanda. Ilizwe elifakiweyo linobuchule obulungileyo, iplastikhi epholileyo eguquguqukayo, kunye ne-weldability engalunganga.
I-65Mn high carbon steel isetyenziselwa ukuveliswa kwemithombo eyahlukeneyo yecandelo elincinci, imithombo ejikelezayo, i-clockwork, njl.

Ukuqulunqwa kwemichiza

Itheyibhile engezantsi idwelisa i-65Mn ephezulu ye-carbon steel chemical composition esekelwe kuhlalutyo lobushushu.

Amanqaku: Iibhari ezinobubanzi kunye nobude becala obungekho ngaphezu kwe-80 mm kunye neentsimbi ezisicaba ezinobunzima obungekho ngaphezu kwe-40 mm.

Ukucaciswa koNyango lobushushu

GB/T 1222	65Mn	830 ± 20	I-oyile	540 ± 20

Inkqubo yokudibanisa: Ubushushu be-Annealing (860 ± 10) °C, ukugcinwa kobushushu kwi-45-60min, ukupholisa iziko ukuya (750 ± 10) °C, ukugcinwa kobushushu kwi-3-3.5h, kunye nokupholisa kweziko ukuya kuma-650-660 °C, emva koko ukupholisa ngaphandle kwesithando somlilo okanye ukupholisa okucothayo kwindawo yokugcina ubushushu.
