65Mn amabha ensimbi ayindilinga ashisayo ashisayo

Insimbi engu-65Mn iyizinga lensimbi elijwayelekile lase-Chinese GB, iManganese (Mn) ithuthukisa ukuqina, ngakho-ke amandla, ukuqina, ukunwebeka nokuba lukhuni kungaphezulu kwalokho kwensimbi engu-65#, kodwa inokuzwela ngokweqile kanye nokufutheka kwentukuthelo. Ukucisha amanzi kuvame ukwenza imifantu. Isimo esishubile sinokusebenza okuhle, i-plasticity ye-deformation ebandayo ephansi, kanye nokushisela okuncane.
I-65Mn high carbon steel isetshenziswa kakhulu ekwenzeni iziphethu eziyisicaba ezihlukene zesigaba esincane, iziphethu eziyindilinga, iwashi, njll. Ingasetshenziswa futhi ukwenza izindandatho zasentwasahlobo, iziphethu zamavalvu, izinto ezibamba ukushisa, umhlanga we-clutch kanye nemithombo yamabhuleki.

Ukwakheka Kwamakhemikhali

Ithebula elingezansi libonisa ukwakheka kwamakhemikhali ensimbi yensimbi engu-65Mn ngokusekelwe ekuhlaziyeni ukushisa.

Amanothi: Amabha anobubanzi nobude obuseceleni obungekho ngaphezu kuka-80 mm nezinsimbi eziyisicaba ezinogqinsi olungekho ngaphezu kuka-40 mm.

Ukucaciswa Kokwelashwa Kokushisa

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

Inqubo yokuhlanganisa: Izinga lokushisa le-annealing (860 ± 10) °C, ukugcinwa kokushisa okungu-45-60min, ukupholisa isithando somlilo kuya ku-(750 ± 10) °C, ukugcinwa kokushisa ku-3-3.5h, kanye nokupholisa kwesithando somlilo kuya ku-650-660 °C, bese ukupholisa ukuphuma esithandweni noma ukupholisa kancane emgodini wokulondoloza ukushisa.
