DX51D Steel yog dab tsi?
DX51D yog qib qis- carbon structural steel qib txhais los ntawm EN 10346, tshwj xeeb yog tsim los rau kev sib sau txias thiab txheej txheej txheej. Thaum ua ke nrog kub -dip zinc txheej,DX51D galvanized hlaudhau los ua ib qho ntawm feem ntau siv kev tsim kho thiab tsim cov khoom siv hauv kev lag luam niaj hnub no.
Lub zinc txheej tsis tsuas yog tiv thaiv cov hlau los ntawm corrosion tab sis kuj tseem txuas ntxiv nws lub neej kev pab cuam, ua DX51D haum rau ntev - siv nyob rau hauv kev xav tau ib puag ncig. Vim tias nws cov khoom siv sib npaug, kev ua haujlwm zoo, thiab muaj zog corrosion kuj, DX51D tau dhau los ua cov khoom siv hauv tsev, kev tsim kho, kev thauj mus los, thiab cov khoom tsim khoom.

Thicker coatings ho txuas ntxiv lub neej ntawm DX51D galvanized steel nyob rau hauv ib puag ncig hnyav.
DX51D vs DX54D: Kev Ua Haujlwm Sib Txawv Tom Qab Galvanizing
DX54D yog qib formability ntau dua piv nrog DX51D thiab feem ntau yog siv rau kev sib sib zog nqus nqus thiab kev ua haujlwm nyuaj. Tom qab galvanizing, ob qib tau txais txiaj ntsig los ntawm kev tiv thaiv corrosion, tab sis lawv tus cwj pwm tsim tseem txawv.
Table 3: Kev sib piv DX51D thiab DX54D
| Khoom | xwm 51d | xwm 54d |
|---|---|---|
| Yield zog (MPa) | Ntau dua lossis sib npaug li 140 | Ntau tshaj los yog sib npaug rau 120 |
| Elongation (%) | Ntau dua lossis sib npaug 22 | Ntau dua lossis sib npaug li 28 |
| Formability | Zoo | Zoo heev |
| Tej kev siv | Ru tsev, vaj tse, panels | Automotive panels, sib sib zog nqus- kos qhov chaw |
| Nqi Efficiency | Siab | Nruab nrab |
DX51D muaj qhov sib npaug zoo heev ntawm kev ua haujlwm ntawm kev ua haujlwm, kev tiv thaiv corrosion, thiab kev ua haujlwm ntawm kev lag luam, ua rau nws qhov kev xaiv zoo tshaj plaws rau kev siv dav dav -.
