Dab tsi yog qhov ceev ntawm S235J0 steel?
Qhov ceev ntawm S235J0 steel yog kwv yees li 7.85 grams ib cubic centimeter (g / cm³), uas yog sib npaug rau 7850 kilograms ib cubic meter (kg / m³) los yog 490 phaus ib cubic feet (lb/ft³).
Tus nqi ntawm qhov ntom ntom no yog qhov zoo rau qis- carbon thiab tsis yog- alloy structural steels (zoo li S235 series) thiab zoo ib yam ntawm cov qib zoo xws li S235JR thiab S275JR, vim qhov sib txawv me me ntawm cov tshuaj muaj pes tsawg leeg ntawm cov qib no tsis cuam tshuam rau lawv qhov ntom ntom.
Ntsiab ntsiab lus:
Qhov ntom ntom no yog siv rau kev ntsuas qhov hnyav hauv kev tsim, logistics, thiab kev kwv yees tus nqi.
Nws assumes khoom, unwrought steel; qhov tseeb qhov hnyav tuaj yeem sib txawv me ntsis nrog kev ua haujlwm ntev, kev ntsuas, lossis qhov chaw saum npoo.
The density remains stable across the temperature range for which S235J0 is designed (up to its melting point).
1. S235J0 steel yog dab tsi?
S235J0 yog ib qho tsis yog - alloy structural steel qib raws li EN 10025-2, nrog rau qhov tsawg kawg nkaus lub zog ntawm 235 MPa thiab lav qhov cuam tshuam toughness ntawm 0℃.
2. Qhov txawv ntawm S235JR thiab S235J0 yog dab tsi?
Qhov sib txawv tseem ceeb yog qhov ntsuas qhov kub thiab txias: S235JR raug kuaj ntawm +20 degree, thaum S235J0 raug kuaj ntawm 0 degree, ua rau nws haum rau qhov chaw txias dua.
