Daim duab peb sab Mild Steel Bar Ss400

Daim duab peb sab Mild Steel Bar Ss400, tseem hu ua A3 steel, yog cov qauv carbon zoo tib yam. Cov khoom siv no muaj cov ntsiab lus carbon tsawg, thiab muaj cov khoom zoo xws li lub zog, plasticity thiab weldability. Nrog rau qhov nce ntawm tuab, nws cov txiaj ntsig tau dhau los ua me dua, thiab nws yog cov khoom siv dav siv hauv kev ua lag luam, feem ntau siv los ua steel tuav lossis lub Hoobkas thav ntawv, thiab tseem tuaj yeem ua cov khoom siv nrog cov kev ua haujlwm tsawg.

Daim duab peb sab Mild Steel Bar Ss400 yog qhov tseem ceeb sib npaug rau Tuam Tshoj Q235 (sib npaug rau Q235A). Txawm li cas los xij, muaj qhov sib txawv ntawm cov ntsuas tshwj xeeb. Q235 xav tau cov ntsiab lus ntawm C, Si, Mn, S, P thiab lwm yam, tseem SS400 tsuas yog xav kom S thiab P tsawg dua 0.050. Qhov taw tes tawm ntawm Q235 tshaj 235 MPa, thaum lub ntsiab lus ntawm SS400 yog 245 MPa. SS400 (steel rau cov qauv dav dav) txhais tau tias lub zog tensile ntawm cov qauv hlau dav dav yog ntau dua 400 MPa. Q235 qhia tau hais tias cov pa roj carbon zoo tib yam nrog cov ntsiab lus tawm los ntau dua 235 MPa. Tus naj npawb ntawm SS400 yog JIS G3101. Tus lej qauv ntawm Q235 yog GB / T700. SS400 yog ib txoj kev kos npe rau Japanese hlau. Qhov tseeb, nws yog lub tsev Q235 steel. Nws yog ib hom khoom siv hlau. Q sawv cev rau cov txiaj ntsig ntawm cov khoom siv no, thiab 235 tom qab nws hais txog cov txiaj ntsig ntawm cov khoom siv no, uas yog kwv yees li 235. Tus nqi tawm los yuav poob qis nrog qhov nce ntawm cov khoom thickness. Vim muaj cov ntsiab lus ntawm cov pa roj carbon monoxide, qhov kev ua tau zoo, nrog rau lub zog, plasticity, thiab vuam zog, tau ua haujlwm zoo thiab yog qhov siv dav tshaj plaws. Nws yog feem ntau dov mus rau hauv cov hlau los yog ntau hom hlau xws li round steel, square steel, ca steel, lub kaum sab xis steel, I-steel, channel steel, qhov rai ncej steel, thiab nruab nrab-thickness steel daim hlau. Nws yog dav siv nyob rau hauv kev tsim kho thiab engineering lug. Nws yog siv los tsim steel tuav los yog tsim cov nroj tsuag thav duab, high-voltage kis tau tus yees, txuas hniav, tsheb, boilers, ntim, nkoj, thiab lwm yam. Nws kuj yog siv dav raws li cov khoom siv nrog cov kev ua haujlwm tsawg. C thiab D qib steel kuj tuaj yeem ua haujlwm rau qee cov hlau tshwj xeeb
