Q35B Txuj Ci Hlau Hlau

Q355B yog cov qauv hlau txheej txheem, feem ntau sib xyaw ntawm cov hlau (kwv yees li 98%), nrog rau cov roj carbon, siliam, manghologe, phosphorus, thiab leej faj. Nws yog feem ntau grey khoom, kub- rolled. Q355B muaj cov cuab yeej zoo heev, suav nrog lub zog siab thiab zoo weldability, ua rau haum rau kev siv hauv kev tsim kho, txuas hniav, thiab tshuab hnyav. Nws tuaj yeem raug cais raws li tuab thiab lees paub lub zog thiab siv dav hauv cov txheej txheem txheej txheem siab thiab kev ntseeg tau.

Ntaub

Q355B Steel muaj lub zog siab, muaj siab heev weldability thiab ductility, thiab corrosion tsis kam, thiab corrosion rau cov ntawv thov hnyav thiab ib puag ncig. Kev kho cua sov tuaj yeem txuas ntxiv nws lub zog, ductility, thiab coj kev tiv thaiv, ua kom muaj kev txhim khu kev qha. Q355B Steel yog feem ntau siv nyob rau hauv cov dov lossis ib txwm muaj lub xeev yam tsis muaj kev kho cua sov ntxiv. Yog tias tsim nyog, normalizing tuaj yeem ua los ua kom ua kom zoo ua kom cov qauv sib dhos thiab txhim kho cov khoom siv neeg txhua yam.

Nto Kho ntawm Q355b Txheej txheem hlau

Kev kho deg ntawm Q35B txheej txheem txheej txheem hlau ua kom txhim kho nws cov huab cua tsis kam thiab kav ntev. Cov txheej txheem sib xws muaj xws li kub - dip galvanizing, epoxy txheej, thiab sandblasting. Ua ntej, tua blasting lossis sandblasting tshem tawm saum npoo oxide nplai thiab impurities, tsim kom huv, ntxhib thauj tog rau cov qauv adhance. Tom qab ntawd, kub - dim galvanizing ua ib epoxy cocosion, lossis} Corrosion Topcoat yog thov los tsim ib qho dual {8}- tiv thaiv system. Cov kev kho mob no ua rau muaj kev cuam tshuam ntawm cov txheej txheem steel hauv ib puag ncig cov kev pabcuam steel nyob rau hauv anti {10}
