DX54D hlau
DX54D, cov hlau tshwj xeeb uas siv hauv ultra- cov txheej txheem sib sib zog nqus canvas stamping, tsis yog tag nrho -crystalline thiab qiv nws tus kheej mus rau qhov tsis zoo. Nws cov yam ntxwv tseem ceeb yog raws li nram no:
Kev ntxhov siab ntawm qhov taw tes tawm los: siab tshaj 280 MPa
Tensile zog: siab tshaj 400 MPa
Elongation zog: yam tsawg kawg nkaus 37% (txog 0.8 thickness)
Kev Ua tiav: Cov neeg siv tuaj yeem xaiv qhov ua tiav lawv nyiam, xws li los ntawm ib txwm mus rau qhov tshwj xeeb tiav
Qhov ntau ntawm thicknesses: Feem ntau, nws txawv ntawm 0.30 hli mus rau 3.00 hli
Txheej: Feem ntau muab rau hauv daim ntawv ntawm zinc thiab hlau los yog zinc ntxiv rau cov hlau kom muaj kev tiv thaiv zoo los ntawm xeb.
dx54d ua. nruj me ntsis, cov neeg siv khoom hnyav hnyav xav tau cov khoom lag luam thiab xa tawm nruj me ntsis rau cov neeg siv khoom yuav xav tau cov khoom zoo li no.

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.
