ss400 yog ib txoj hauv kev kos npe rau Japanese steel, qhov tseeb, nws yog cov khoom siv Q235 steel. Nws yog cov khoom siv hlau. Q sawv cev rau cov txiaj ntsig ntawm cov khoom siv no, thiab 235 qab yog hais txog tus nqi tawm los ntawm cov khoom siv no, uas yog hais txog 235. Tus nqi tawm los yuav txo qis nrog qhov nce ntawm cov thickness ntawm cov khoom. Vim muaj cov ntsiab lus ntawm cov pa roj carbon monoxide, kev ua haujlwm zoo, lub zog, plasticity thiab vuam cov khoom tau zoo sib xws, feem ntau siv dav.
ss400 feem ntau dov rau hauv cov hlau los yog puag ncig steel, square steel, ca steel, Lub kaum sab xis steel, I- steel, channel steel, qhov rai ncej steel thiab lwm yam hlau, nruab nrab thickness steel phaj. Dav siv nyob rau hauv kev tsim kho thiab engineering cov qauv. Nws yog siv los ua steel tuav los yog tsim cov ntoo ncej, siab -voltage transmission towers, Choj, tsheb, boilers, ntim, nkoj, thiab lwm yam., thiab kuj yog dav siv los ua txhua yam khoom uas yuav tsum tau ua haujlwm tsawg. C, D qib steel kuj tseem siv tau rau qee cov hlau ua haujlwm.
Lub kaum sab xis steel, tseem hu ua Angle hlau, yog steel bar nrog ntsug kaum ntawm 90 degrees ntawm ob sab, muab faib ua lub kaum sab xis steel thiab tsis sib npaug Lub kaum sab xis; Lub kaum sab xis steel yog ib qho yooj yim seem steel siv nyob rau hauv lub tsev tsim, yog carbon structural steel; Nws yog tsuas yog siv rau cov khoom siv hlau thiab cov nroj tsuag thav ntawv, yog li ntawd lub kaum sab xis steel yuav tsum muaj qhov zoo weldability, yas deformation thiab tiv taus qee yam khoom siv zog.
