Q235 Q275 Lub kaum ntse ntse hlau
Q235 yog cov khoom siv carbon steel. Cov pa roj carbon steel yog cov hlau uas muaj hlau thiab carbon, tab sis cov ntsiab lus carbon tsawg dua 2%. Tseem muaj qee qhov me me ntawm silicon, manganese, sulfur, thiab phosphorus. Cov hlau uas muaj leej faj thiab phosphorus nrog cov ntsiab lus ntau dua 0.35% tab sis tsawg dua 0.5% yog hu ua "cov pa roj carbon zoo tib yam". Cov ntsiab lus ntawm sulfur nyob rau hauv high carbon steel thiab high carbon steel yog tsawg heev, thaum cov sulfur thiab phosphorus cov ntsiab lus nyob rau hauv high carbon steel yog ob qho tib si hauv qab no 0.3%.
Q275 yog ib hom carbon structural steel hauv Suav teb. Lus Askiv "Q" txhais tau tias "yield point", uas txhais tau tias "yield point", uas kuj yog "yield zog". "275" txhais tau tias chav tsev nqi ntawm "275", thiab lub zog tensile nyob nruab nrab ntawm 410 thiab 540 MPa.

Khoom Description
Cov npoo sib npaug thiab tsis sib npaug yog ob hom tseem ceeb ntawm Q235 Q275 Lub kaum ntse ntse hlau. Lub kaum sab xis yog khoov siv ib lub tiaj tiaj steel profile. Nws yog feem ntau tsim ntawm lub kaum sab xis ntawm 90 degrees thiab ob txhais ceg yog qhov loj tib yam. Hauv qab no yog cov lus piav qhia ntxaws txog ntau hom kaum sib txawv:
Sib npaug kaum
Cov kaum sib npaug muaj ob axes ntawm tib qhov ntev, yog li lub npe. Lawv yog hom kaum feem ntau. Lawv tuaj yeem tsim rau ntau yam kev qhia tshwj xeeb thiab tuaj yeem txiav rau txhua qhov loj. Yog li ntawd, lawv yog ntau ntau yam. Lawv qhov ntev yog qhia raws li A sab x B sab x thickness.
Lub kaum sab xis
Lub kaum sab xis tsis sib xws kuj yog txoj cai - kaum sab xis, tab sis lawv muaj qhov sib txawv axis thiab yog L- zoo li. Tshooj lus no muaj lub zog ntau dua (txog 20%) thiab lub zog siab dua - rau - qhov hnyav piv. Qhov ntev yog qhia raws li A-sab x B-sab x thickness.
