DC03 Cold Rolled Steel yog dab tsi?
DC03 txias dov hlau yog qis- carbon steel tsim los txhim kho formability piv rau kev lag luam- qib zoo. Nws muaj qhov zoo elongation thiab ruaj khov deformation tus cwj pwm, ua rau nws haum rau khoov, stamping, thiab nruab nrab daim ntawv thov.
Raws li daim ntawv thov, DC03(St13) txias- dov qis carbon steel yog siv los kos duab zoo. Nrog rau kev kos duab zoo thiab vuam kev ua tau zoo thiab qhov tseeb qhov tseeb, DC03(St13) txias- dov qis carbon steel tau dav siv los tsim ntau yam khoom siv tsheb.
