S235J0 rau S235JR steel yog ob hom qauv hlau uas feem ntau siv hauv kev tsim vaj tsev thiab kev tsim vaj tsev. Ob leeg ntawm cov qib steel no yog ib feem ntawm EN 10025-2 tus qauv, uas yog ib qho kev sau ntawm cov qauv hlau tshwj xeeb uas npog cov khoom siv kub kub siv rau kev tsim qauv.
Qhov sib txawv tseem ceeb ntawm S235J0 thiab S235JR steel yog tias S235J0 tsis yog tsim los siv rau hauv cov qauv siv thaum S235JR yog. Qhov no yog vim S235J0 tsis yooj yim tsim thiab tsis muaj cov khoom zoo weldability. Ntawm qhov tod tes, S235JR yog qhov tsim nyog rau kev siv cov qauv thiab yog yooj yim formable thiab weldable.
Hais txog cov tshuaj muaj pes tsawg leeg, S235J0 thiab S235JR steel yog ob qho tib si tsim los ntawm hlau, carbon, thiab lwm yam. Txawm li cas los xij, cov tshuaj muaj pes tsawg leeg ntawm txhua qib sib txawv me ntsis. Piv txwv li, S235J0 muaj cov pa roj carbon ntau dua li S235JR. Tsis tas li ntawd, S235J0 muaj cov manganese ntau dua li S235JR.
Hais txog cov khoom siv kho tshuab, S235J0 thiab S235JR steel muaj cov txiaj ntsig zoo sib xws thiab lub zog tensile. Txawm li cas los xij, S235J0 muaj tus nqi qis qis dua li S235JR. Qhov no yog vim qhov tseeb tias S235J0 tsis yog tsim los siv rau hauv cov qauv siv thiab tsis yooj yim tsim.
Zuag qhia tag nrho, S235J0 thiab S235JR steel yog ob hom qauv hlau uas feem ntau siv hauv kev tsim vaj tsev thiab kev tsim vaj tsev. Qhov sib txawv tseem ceeb ntawm lawv yog tias S235J0 tsis yog tsim los siv rau hauv cov qauv siv thaum S235JR yog. Tsis tas li ntawd, S235J0 thiab S235JR steel muaj cov tshuaj sib txawv me ntsis thiab cov khoom siv kho tshuab.
