Khoom Taw Qhia thiab Thov
20cr1mo1vnbtib yog hom high-zog bolt steel tsim rau ib puag ncig kub.
20cr1mobblb steel steel belong belong belong belong belong belong belong belong belong bears steel nyob rau hauv koob ntawm low alloy zog steel, uas yog cov hlau zoo tsim los ntawm peb lub teb chaws. Nws muaj cov qib siab ntawm chromium (CR), Molybdenum (MO), thiab cov khoom siv ntawm cov roj av, thiab cov khoom siv ntawm cov hlau, thiab muaj peev xwm ua kom zoo dua ntawm cov hlau, thiab nws muaj peev xwm txhim kho cov roj av cov khoom ntawm cov kub kub1.
Cov hlau muaj siab so kom tsis kam ntawm qhov kub ntawm 570, uas txhais tau tias nws cov duab thiab tsis muaj qhov sib luag thiab tsis muaj peev xwm ua tau zoo thiab tsis muaj peev xwm ua tau zoo thiab tsis muaj peev xwm ua tau zoo thiab tsis muaj peev xwm ua tau thiab tsis muaj peev xwm ua tau zoo thiab tsis muaj peev xwm ua tau thiab tsis muaj peev xwm ua tau thiab tsis muaj peev xwm ua tau thiab tsis muaj peev xwm ua tau zoo thiab tsis muaj peev xwm ua tau zoo thiab tsis muaj peev xwm ua tau zoo thiab tsis muaj peev xwm ua tau zoo thiab tsis muaj peev xwm ua tau zoo thiab tsis muaj qhov sib luag Nyob rau tib lub sijhawm, nws kuj muaj lub zog loj thiab ua kom muaj txiaj ntsig zoo, thiab muaj peev xwm tswj tau cov khoom muaj peev xwm zoo ntawm cov kev ntxhov siab ntau. Tsis tas li ntawd, 20cr1mo1vnndib alloy steel muaj tsawg cov ntaub ntawv ruaj khov, thiab zoo cov khoom siv rau kev kub siab rau cov high-kub thiab lwm yam tseem ceeb.
Hauv kev siv cov tswv yim, 20cr1meej1vnblimter steel tau siv dav hauv cov khoom tseem ceeb hauv cov hluav taws xob siab loj, xws li cov xim kub hauv plab, qhia nws cov txiaj ntsig zoo.
Hauv cov ntsiab lus, 20cr1mo1vnbtib high-zog pob zeb steel muaj nyob rau hauv daim ntawv thov ntawm cov khoom kub kub thiab kub-kub ruaj khov.
