DX54D Steel yog dab tsi?
DX54D yog kub-dip coated sib sib zog nqus- kos hlau nyob rau hauv DX series, muaj nuj nqis rau siab formability. Ua los ntawm qis- carbon steel, nws zoo tagnrho rau kev sib sau txias. "DX" qhia cov koob, "54" qib formability, thiab "D" qhov tob- kos duab zoo. Ob leeg DX54D thiab DX53D yog cov tsheb hlau, tab sis DX54D muaj ntau dua formability, ua rau nws zoo dua rau cov duab complex. DX54D (sib npaug rau FeP06G, steel tooj 1.0952) yog siv nyob rau hauv automotive panels thiab cov khoom vaj tse, nrog corrosion kuj rau sab nraum zoov los yog ntub dej.

Cov pa roj carbon tsawg (C): Ua kom ductility thiab yooj yim hauv kev sib sib zog nqus nqus yam tsis muaj kev cuam tshuam lub zog.
Tswj Manganese (Mn): Txhim khu lub zog thiab toughness.
Tsawg Phosphorus (P) thiab Sulfur (S): Txhim kho weldability thiab txo brittleness.
Aluminium (Al): Ua raws li deoxidizer, txhim kho qhov zoo.
Titanium (Ti): Ua kom muaj kev ruaj ntseg hauv kev tsim, txo cov kab nrib pleb thiab qhov tsis xws luag thaum shaping.

| Anisotropy (R-Tus nqi, Min) | Ntau dua lossis sib npaug rau 1.6 | Ntau dua lossis sib npaug rau 1.6 |
| Strin Hardening Index (n-Tus nqi, Min) | Ntau dua lossis sib npaug rau 0.18 | Ntau dua lossis sib npaug rau 0.18 |
Nruab nrab Tensile thiab Yield Strength: Muab lub zog txaus rau kev ua haujlwm ntev yam tsis muaj kev cuam tshuam kev tsim kho, haum rau tsheb thiab khoom siv.
High Elongation: Tso cai stretching tseem ceeb, ua kom cov duab tsis muaj cracking.
Zoo Anisotropy (R-Value): Ua kom cov khoom sib xws hauv cov lus qhia sib txawv, txo qhov tsis xws luag hauv qhov sib sib zog nqus- kos.
Stable Strain Hardening Index (n-Tus nqi): Txhawb gradual deformation, uas pab tswj cov txheej txheem kev ncaj ncees thaum lub sij hawm shaping.
