Cov khoom siv twg yog DC02 sib npaug rau?
DC02 yog cov muaj pa roj carbon ntau, tsawg-alloy txias-ua haujlwm tuag hlau, nrog rau lub teb chaws lub teb chaws (G1}}} Raws li txias stamping tuag thiab ntsuas cov cuab yeej. Cov ntaub ntawv zoo sib xws xws li American AISI L3, European 100CR6 (DIN 1.2067) thiab Japanese SuJ2 (cov kabmob hlau). Nws yog tus cwj pwm los ntawm kev hardness siab (hrc 60+) Thiab hnav tsis kam, tab sis yog qhov tsim nyog rau cov cuab yeej tsawg thiab tuag.
Dab tsi yog qhov sib txawv ntawm DC02 thiab DC05?
DC02 yog cov roj carbon muaj ntau cov hlau uas muaj pes tsawg leeg nrog cov khoom sib xyaw ua ke lossis 0.2% ~ 1.0% cr), gauges, thiab tej cuab yeej tsawg DC05 yog raws li DC02 thiab ntxiv ib qho me me ntawm alloy cov ntsiab lus (xws li 0.5% mo los yog kab ntawv nrog cov khoom siv hluav taws xob ntau dua (xws li cov khoom siv hluav taws xob ntau dua thiab kos duab tuag).
Puas yog DC02 cov hlau me?
Cov pa roj carbon cov ntsiab lus ntawm DC02 feem ntau yog nruab nrab 0 {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} DC02 tsis yog cov roj carbon hlau tsawg, tab sis cov pa roj ntau cov hlau, uas yog siv rau kev hnav khaub ncaws-resistant xws li ua haujlwm txias, thiab ntsuas cov cuab yeej.
