Carbon (c): Muab lub zog tab sis txo cov qauv sib xws. S235JRH muaj cov ntsiab lus muaj roj carbon tsawg, uas ua kom muaj kev pom zoo kom zoo thiab weldability.
Manganese (mn): Txhim kho lub zog thiab hardness yam tsis muaj kev txo qis dua.
Phosphorus (p) thiab Sulphur (s): Cov ntsiab lus no feem ntau tsis xav tau raws li lawv tuaj yeem txo kev sib luag thiab tawv. Lawv cov ntsiab lus yog txwv tsis pub tsawg hauv s235jrh kom ntseeg tau zoo cov khoom siv.

Lub zog: S235JRH muaj cov kev thov muaj txiaj ntsig txaus rau cov kev thov thaum tswj hwm kev ua kom zoo thiab muaj peev xwm.
Kev ua siab loj: Feem pua EVongation siab ua kom muaj txiaj ntsig tias cov khoom tuaj yeem tiv thaiv tsis zoo li tsis muaj pob zeb, ua rau nws haum rau kev txias thiab vuam.
Kev Cuam Tshuam: Cov khoom siv tau zoo ntawm chav sov, kom ntseeg tau tias kev ntseeg tau rau hauv cov ntawv thov txheej txheem.
Kev sib piv nrog lwm cov qauv steel
S275J0H/S275J2H: Cov qhab nia tau nce siab dua thiab cov txiaj ntsig tensile (tsawg kawg yog lub zog muaj zog ntawm 275 MPA) tab sis qis elongation (yam tsawg kawg nkaus ntawm 20%) piv rau S235JRH. Lawv tsim nyog rau cov ntawv thov uas xav tau lub zog siab dua tab sis yuav tsawg dua.
S355J0H/S355J2H: Cov qib no muaj ntau dua lub zog (yam tsawg kawg yog lub zog ntawm 355 MPa) thiab yog qhov zoo tagnrho rau cov qauv hnyav-load. Txawm li cas los xij, lawv tau qis dua kev txhim kho thiab yuav xav kom ceev faj ntau ntxiv thaum tsim thiab vuam.
Cov noob nplej zoo (piv txwv li, s275nh / s355nh): Cov qib kawm muaj cov khoom zoo sib xws tab sis yog tsim rau cov ntawv thov tshwj xeeb lossis siv cov xwm txheej. Lawv tuaj yeem muab cov tawv tawv zoo dua ntawm qhov kub qis piv rau cov qib tsis yog-alloy.
Qhov Zoo
Siab zog-rau-qhov hnyav piv:
Cov txheej txheem txias siv nyob rau hauv kev tsim khoom rau kev tsim khoom EN 10219 S235 raj ua rau lub teeb ci ntsa iab tsis tau muaj cov qauv muaj zog. Qhov no txo qhov hnyav tag nrho ntawm kev tsim kho cov haujlwm yam tsis muaj kev cuam tshuam nrog lub zog.
Zoo Weldability:
Qhov "JRH" hauv S235JRH qhia tias cov khoom no yog tsim rau Welded qauv. Nws zoo heev weldability ua kom muaj zog thiab ntseeg tau tias nws zoo tagnrho rau ntau yam kev ua haujlwm ua ke yog qhov tseem ceeb.
Nqi-txiaj ntsig:
Lub zog siab ntawm EN 10219 S235 tso cai rau kev siv cov ntu thinner, txo cov nqi khoom. Ib qho ntxiv, kev ua tau zoo ntawm cov ntu ua kom tiav txo lub sijhawm tsim kho, ntxiv txhim kho tus nqi them ntxiv.
Versatility hauv kev tsim
Muaj nyob rau hauv ntau cov duab (puag ncig, square, thiab duab plaub), s235 raj muaj cov qauv tsim qauv uas tau raws li kev ua kom zoo nkauj thiab ua haujlwm kom haum. Cov versatility no tso cai rau kev tsim kho tshiab thiab kev tsim qauv zoo nkauj.
