Nov yog qee cov yam ntxwv tseem ceeb ntawm Q355D steel:
1, Chemical Composition: Cov tshuaj muaj pes tsawg leeg ntawm Q355D steel yuav txawv nyob ntawm tus qauv tshwj xeeb lossis cov chaw tsim khoom. Txawm li cas los xij, cov ntsiab lus tseem ceeb suav nrog carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), thiab cov lej ntawm lwm cov alloying xws li niobium (Nb), vanadium (V), thiab titanium. (Ti) txhawm rau txhim kho cov khoom siv lub zog thiab cov khoom siv kho tshuab.
2, Mechanical Properties: Q355D steel muaj lub zog ntau dua piv rau cov qauv carbon zoo li Q235 thiab Q345. Nws feem ntau nthuav tawm lub zog ntau dua, lub zog tensile, thiab cuam tshuam toughness.
3, Daim Ntawv Thov: Q355D steel yog dav siv nyob rau hauv ntau yam kev siv, nrog rau kev tsim vaj tsev thiab choj, kev tsim tshuab, kev tsim tawm sab nrauv, thiab lwm yam haujlwm engineering uas yuav tsum tau muaj zog thiab kav ntev.
4, Kev kho cua sov: Q355D steel tuaj yeem dhau los ua ntau yam kev kho cua sov, xws li quenching thiab tempering, txhawm rau txhim kho nws cov khoom siv kho tshuab.
