To taub covDX51D qib sib npaugthiab nws ua li cas tiv thaiv cov qib formability siab dua xws li DX53D thiab DX54D yog qhov tseem ceeb rau kev xaiv cov khoom siv hauv kev tsim kho, stamping, khoom tsim khoom, thiab cov khoom siv tsheb. DX51D, txhais raws li EN 10346, yog feem ntau siv kub-dip galvanized steel rau kev sib sau txias. Los ntawm kev qhia meej txog nws qhov sib npaug thoob ntiaj teb thiab sib piv nws cov khoom siv tshuaj, khoom siv, thiab cov khoom siv nrog DX53D thiab DX54D, cov neeg yuav khoom thiab cov kws tsim khoom tuaj yeem txiav txim siab kom raug rau qhov sib npaug ntawm tus nqi, kev tsim, thiab kev ua haujlwm.
Dab tsi yog DX51D Sib npaug Qib hauv Ntiaj Teb Cov Qauv?
DX51D yog qib European tus qauv, thiab ntau lub lag luam hlau loj muaj cov qhab nia sib npaug lossis ua haujlwm sib npaug. Cov khoom sib npaug no qhia cov tshuaj muaj pes tsawg leeg zoo sib xws, cov khoom siv kho tshuab, thiab daim ntawv thov, ua rau lawv hloov pauv tau hauv ntau qhov haujlwm.
Cov lus hauv qab no qhia covDX51D qib sib npaughauv cov txheej txheem sib txawv:
| Standard System | Qib sib npaug | Lus ceeb toom |
|---|---|---|
| European Txuj (EN 10346) | TX51D (1.0226) | Original standard qib |
| Suav GB (GB/T 2518) | DX51D + Z / SGCC | Feem ntau siv sib npaug hauv Suav teb |
| Asmeskas ASTM | ASTM A653 CS Hom B / G60 G90 | Functional sib npaug rau kev sib sau thiab txheej |
| Japanese JIS | SGCC | Feem ntau sib npaug hauv East Asian lag luam |
| Korean KS | SGCC | Ua raws li tus qauv Japanese sib npaug |
Tag nrho cov qib no yog tsim los rau kev ua kom txias txias, nrog cov ntsiab lus carbon tsawg, sib npaug zog thiab ductility, thiab zoo sib xws nrog kub -dip galvanizing. Thaum xaiv ibDX51D qib sib npaug, cov txheej thickness (Z, AZ, AM) thiab qhov ntev ntev yuav tsum tau sib phim raws li qhov yuav tsum tau ua.
Kev sib piv tshuaj muaj pes tsawg leeg: DX51D vs DX53D vs DX54D
Qhov sib txawv tseem ceeb ntawm DX51D, DX53D, thiab DX54D nyob rau hauv cov tshuaj muaj pes tsawg leeg, tshwj xeeb tshaj yog cov pa roj carbon thiab microalloy khoom tswj. Cov pa roj carbon tsawg dua thiab cov kev txwv tsis pub muaj kev txwv tsis pub muaj kev sib sib zog nqus sib sib zog nqus -drawability, uas yog vim li cas DX53D thiab DX54D tau siv los ua ntau txoj hauv kev.
Tag nrho peb qib ua raws EN 10346, tab sis lawv qhov txwv tsis pub muaj qhov sib txawv:
xwm 51d: Cov ntsiab lus carbon ntau dua, haum rau khoov, yob txoj kev, thiab yooj yim stamping.
xwm 53d: Ultra- carbon qis, feem ntau ruaj khov nrog titanium lossis niobium, siv rau kev kos duab sib sib zog nqus.
xwm 54d: Cov pa roj carbon tsawg heev thiab siab elongation, tsim rau kev sib sib zog nqus nqus thiab siab -precision shaping.
- Hom tshuaj muaj pes tsawg leeg (wt%):
Cov pa roj carbon (C): DX51D Tsawg dua lossis sib npaug rau 0.12, DX53D Tsawg dua lossis sib npaug rau 0.08, DX54D Tsawg dua lossis sib npaug 0.06
Manganese (Mn): DX51D Tsawg dua lossis sib npaug rau 0.60, DX53D Tsawg dua lossis sib npaug rau 0.50, DX54D Tsawg dua lossis sib npaug 0.40
Phosphorus (P) & Sulfur (S): Kev nce qib qis los ntawm DX51D rau DX54D
Hlau (Fe): Tseem nyob hauv txhua qib
Txo cov pa roj carbon thiab impurities txo hardness thiab nce ductility, tso cai rau cov hlau tiv taus ntau dua deformation yam tsis muaj cracking.
Mechanical Properties Comparison: DX51D vs DX53D vs DX54D
Mechanical kev ua tau zoo ncaj qha txiav txim siab formability. Cov lus hauv qab no sib piv cov cim tseem ceeb ntawm peb qib raws li cov qauv kev xeem:
| Yam khoom | xwm 51d | xwm 53d | xwm 54d |
|---|---|---|---|
| Tensile zog (MPa) | 270 – 500 | 270 – 450 | 270 – 420 |
| Yield zog (MPa) | Tsawg dua los yog sib npaug rau 360 | Tsawg dua lossis sib npaug li 320 | Tsawg dua los yog sib npaug li 280 |
| Elongation (A80,%) | Ntau dua lossis sib npaug 22 | Ntau dua lossis sib npaug li 26 | Ntau tshaj los yog sib npaug rau 30 |
| Qib Formability | Kev tsim qauv | Daim duab sib sib zog nqus | Kev kos duab sib sib zog nqus |
| Hom r-tus nqi | Ntau dua lossis sib npaug rau 1.0 | Ntau dua lossis sib npaug rau 1.4 | Ntau dua lossis sib npaug rau 1.6 |
Los ntawm DX51D mus rau DX54D, lub zog tensile thiab lub zog tawm los maj mam txo qis, thaum elongation thiab r- tus nqi (plastic strain ratio) maj mam nce. Siab dua r- tus nqi txhais tau hais tias zoo dua tiv thaiv thinning thaum lub sij hawm deformation, uas yog qhov tseem ceeb rau qhov nyuaj.
Formability & Application Differences
