1. ** Yog dab tsi S235JR 1.0037 khoom? **
S235JR (Cov Khoom Siv Nyiaj 1.0037) yog qhov tsis-} Alloy alllo qauv hlau qauv hauv kev ua 10025 {10. Qhov "s" sawv rau cov qauv hlau ua yeeb yam, "235" qhia qhov tsawg kawg nkaus zog zog (RH) ntawm 235 MPa thaum 16 hli thickness. "Jr" qhia tias nws tau raug kev cuam tshuam tau sim ntawm chav tsev kub ({8}} degree) nrog qhov tsawg kawg nkaus teev lub zog. Nws yog ib qho dav dav-hom phiaj steel steel dav siv hauv kev tsim kho, thav duab, thiab lwm yam cuab yeej siv zoo vim nws qhov zoo weldability thiab firitability.
2. ** Dab tsi yog sib npaug rau S235 khoom? **
Pom cov sib npaug sib npaug thoob plaws ntawm cov qauv sib txawv yog qhov nyuaj vim yog cov cai sib txawv. Txawm li cas los xij, cov khoom siv feem ntau suav tias ua haujlwm ua haujlwm zoo sib xws lossis siv hauv cov ntawv thov sib piv suav nrog:
* ** AVTM A36 (USA): ** Feem ntau sib piv, zoo sib xws.
* ** JIS G3101 SS400 (Nyiv): ** Zoo ib yam li cov txiaj ntsig cov txiaj ntsig lub zog thiab cov qauv kev siv ua ke.
* ** GB / T 700 Q235 (Suav teb): ** Cov qauv txheej txheem zoo sib xws thiab cov khoom.
* ** DIN ST37-2 (Laus German Txuj): ** Tus thawj coj rau S235JR.
* ** EN 10025-2 S235J0 / S235J2: ** VARIALS NTAWM S235 nrog cov kev cuam tshuam nyuaj sib txawv yuav tsum muaj.
Nco ntsoov xyuas cov kev cai tshwj xeeb ua ntej hloov chaw.
3. ** Dab tsi yog qhov txawv ntawm S235JR thiab S235J0? **
Cov txiaj ntsig sib txawv nyob hauv lawv cov kev cuam tshuam nyuaj yuav tsum muaj ntawm kev sib txawv tam sim no **, qhia los ntawm daim ntawv qhia:
* ** S235JR: ** Cuam Tshuam Tested thaum ** +20}℃(chav sov) **. Yam tsawg kawg nkaus nruab nrab Charpy v - negch cuam tshuam lub zog yog 27 joules.
* ** S235J0: ** Cuam Tshuam Tested ntawm ** 0℃**. Yam tsawg kawg nkaus nruab nrab Charpy V {{4 4}} negch cuam tshuam lub zog yog 27 joules.
S235J0 muaj zoo dua lav cov tawv me me ntawm qis dua kub tshaj S235JR, ua rau nws tsim nyog rau cov ntawv thov kom txias. Tshuaj lom neeg tshuaj lom neeg thiab tawm / tensile lub zog yuav tsum muaj yog lwm yam zoo sib xws.
4. ** Yog S235 steel machinability? **
Yog lawm, S235 steel feem ntau muaj ** zoo machinity muaj **. Raws li qhov qis - carbon, tsis {- alloy} Cov hlau alleoy Qhov no tso cai rau yooj yim dua txiav, drilling, milling, thiab tig nrog kev tooling tooling thiab tsim nyog nrawm / txau. Txawm li cas los xij, nws cov mos mos tuaj yeem ua rau tsim - up ntug lossis crush. Siv cov khoom siv ntse, cov kua dej kom zoo, thiab cov kev ua kom zoo ua kom paub meej qhov txiaj ntsig zoo tshaj plaws.
5. ** Yog A36 sib npaug rau S235? **
ASTM A36 (Tebchaws Asmeskas) yog ** feem ntau suav hais tias yog qhov zoo tshaj plaws (thaj chaw zoo ib yam li 3 hli, thiab lwm yam. Txawm yog li, lawv yog **
* ** A36 feem ntau tso cai me ntsis ntau dua cov pa roj carbon, thiab cov sulphorus, thiab muaj kev sib cav sib ceg, thiab muaj ntau yam ntawm cov ntsiab lus.
* ** TENSILE lub zog: ** A36 yuav tsum tau nce siab tshaj plaws tensile lub zog (400-550 mpa) piv rau S235JR (360-510 MPA).
* ** KEV PAB
Thaum nquag siv sib pauv rau ntau cov ntawv thov, kev thov tseem ceeb lossis cov cai yuav tsum tau ua tiav yuav tsum siv ib tus qauv dhau lwm tus. Nco ntsoov txheeb xyuas qhov haum raws li cov kev qhia tshwj xeeb.
