Zoo elasticity thiab plasticity ntawm caij nplooj ntoos hlav steel, khoom siv kev lag luam, zoo hardenability nyob rau hauv kev kho cua sov, tsis kub cua sov thiab yooj yim deformation yuav siv tau rau pom hniav nrog tsawg txiav yuav tsum tau.
Cov cuab yeej siv roj carbon steel nrog cov pa roj carbon high thermal conductivity, tab sis raug rau 200 ℃ -250 ℃ qhov kub thiab txias, nws lub hardness thiab hnav tsis kam poob nqis, kev kho cua sov deformation, tsis muaj tawv tawv, ntev ntev tsis yooj yim tawg. Kev tsim cov khoom lag luam rau cov cuab yeej txiav xws li T8A, T10A, T12A, thiab lwm yam.
C. Alloy twj hlau tau zoo thaum tshav kub kub ua hauj, abrasion tsis kam thiab kev kho cov cuab yeej sib piv nrog cov cuab yeej carbon hlau. Qhov kub tiv thaiv kub tsis kam tiv thaiv qhov kub kub txog 300 ℃ -400 ℃ yog qhov tsim nyog rau kev tsim cov qib high-qib alloy ncig txuas hniav.
4. Kev kub ceev cov cuab yeej steel muaj qhov zoo hardenability, muaj zog hardness thiab rigidity, thiab me ntsis kub tsis kam deformation. Nws yog ultra siab lub zog hlau nrog thermoplastic stability haum rau kev tsim cov khoom lag luam qib siab ultra-nyias pom tuaj.
