EN10210 Steel Kav

Txheej txheem cej luam ntawm cov qauv:
Tus txheej txheem EN10210 series yog kev qhia tshwj xeeb tsim los ntawm European Union cov qauv ntawm European Union Cov Qauv Siv Kev Tsim Kho (CPR 305/2011 / EU). Nws yog feem ntau tsim nyog rau cov tsev (xws li cov tsev, cov choj, cov qauv kev tshuaj xyuas cov khoom siv hluav taws xob, thiab duab sib dhos, duab dhos, oval, thiab lwm yam).

Khoom Ntau Yam thiab Cov Hlau Uas Raug Hlau:
1. Cov Khoom Siv Muaj
• Txheej ntau txoj kab uas hla: tsawg dua los yog sib npaug nrog 2500 hli, phab ntsa tuab tsawg dua lossis sib npaug rau 120 hli.
• Cov qauv steel yog suav nrog:
• Cov hlau uas tsis-alholesoy: s235jrh, s275J 0 h, s355j2h, thiab lwm yam.
• Ncuav cov qoob loo nplua hlau steel: s255Nlh, s460ndh, thiab lwm yam.

2. Cov Khoom Siv Kev Sib Tw
• Qhov sib txawv ntawm cov hlau tsis sib xws thiab cov tshuaj lom neeg yog cov tshuaj lom neeg thiab cov qoob loo ntawm cov khoom siv los ntawm kev ua kom zoo dua qub thiab lwm cov ntsiab lus txhawm rau txhim kho lub zog thiab tawv.

Kev xav tau
1. Qhov seem tsis kam
• Txheej hauv lub taub kom kam rau: ± 1% (min. 0. 5mm, max. ± 10mm)
• Daim phab ntsa thickness kam kam: -10% (zoo sib txawv yog txwv los ntawm qhov hnyav);
• Ntev ntev: qhov loj me (4m tsawg dua lossis sib npaug ntawm l tsawg dua lossis sib npaug nrog 6m) tso cai rau kev sib txawv ntawm ± 10mm.

2. Tshuaj lom neeg sib xyaw
• Piv txwv ntawm cov hlau tsis muaj tseeb (S355J2H ua piv txwv):
• C Tsawg dua lossis sib npaug ntawm {{{0}}}. 22%, p tsawg dua los yog sib npaug lossis sib npaug 0.030%.
• Piv txwv zoo Cov kab ke me me (S460NH ua piv txwv):
• C Tsawg dua lossis sib npaug ntawm {{{{0}. 2%, thiab kev tswj hwm n tsawg dua los yog sib npaug rau 0.025%.

3. Cov Khoom Siv Kho Tshuab
• Pais lub zog: Qhov tsawg kawg qhov tseem ceeb ntawm 235MPA (s235JRH) rau 460Mpa (s460NH) rau cov qauv steel kawm sib txawv;
• Lub zog tensile: piv txwv li, lub zog tensile ntawm s355j2h yog} mpa mpa cia {3 {3}} mm).

4. Lwm cov kev xav tau
• Weldability, kev cuam tshuam kev ua yeeb yam, xwm txheej kev ua si (oxide, olide, thiab lwm yam raws li ROHS txwv).

Cov Ntawv Thov:
EN10210 steel yeeb nkab yog dav siv nyob rau hauv:
• Tsev qauv hlau (xws li chaw ntau pob, cov tsev siab ceev);
• Siv Machinery (Crane Boom, Excavator qauv);
• Thauj cov kabmob rau cov khoom siv tua hluav taws thiab cov choj.

Txawv steel qib (xws li s235jrh, s275J 0 h, s355j2h, thiab lwm yam) lub ntsiab sib txawv
Txawv hlau qib sib txawv hauv qab en {{{{{}}}}}}}}}) feem ntau cuam tshuam rau qhov sib txawv hauv lawv cov ntawv teev npe.

Cov tub ntxhais sib txawv ntawm qib steel
1. Puture lub zog thiab tensile lub zog
• S235JRH: Tsawg kawg vim muaj lub zog ntawm 235 MPa, tensile lub zog ntawm {2}} MPa, haum rau cov xwm txheej tsis tshua muaj.
• s275J {{0 h / s275j2h: Tshaj tawm lub zog 27}} mpa mpa}} mpa mpa, suav nrog lub zog, noj rau hauv kev lag luam nyiaj txiag thiab kev ua tau zoo.
• S355J {{0 h / s355j25 mpa}} mpa}} mpa, haum rau cov choj kev ntxhov siab (xws li txuas ntxiv cov qauv kev sib txuas lus).

2. Tshuaj lom neeg sib txawv
• Cov ntsiab lus ntawm cov pa roj carbon (c), manganese (mn), phosphorus (p), leej faj (cov) thiab lwm cov ntsiab lus ntawm cov qauv steel sib txawv yog txwv. Piv txwv li, S355 series muaj cov ntsiab lus manganese siab dua, uas txhim kho lub zog thiab tawv.

3. Kev cuam tshuam cov cai tawv tawv
• Cov kab lus profix "j {{{{{{{{}}}}}}}} degree (xws li s355j2h yog qhov haum rau thaj chaw txias).

Daim Ntawv Thov Txawv
1. Cov qauv tsim tsev
S235JRH: Rau cov tsis muaj kev sib tw-cov kabmob lossis cov khoom siv ntxhov siab tsawg (piv txwv li cov kab sib tw me me).
• s275J {0 h: nquag muaj nyob rau hauv dog steel ncej, kev txhawb nqa pem teb thiab lwm yam xwm txheej nruab nrab.

2. Lub zog thauj khoom siab lossis ib puag ncig muaj zog
• S355j2h: Nws yog qhov xav tau rau cov choj, kev nce qib tsev txhawb nqa, thiab kev lag luam cog kev lag luam uas yuav tsum tau tiv thaiv hnyav lossis kev co.

3. Ib puag ncig kub thiab kub tsawg
• Cov qib kev hlau nrog "J2H" Suffix (xws li S355j2H): Haum rau thaj chaw txias, vim tias nws qhov kev cuam tshuam kub tsawg.

Kev xaiv lub hauv paus
• Cov khoom yuav tsum tau ua: Xaiv S355 series rau cov xwm txheej nrog loads siab.
• Ib puag ncig qhov kub: tsawg zaus ib puag ncig yuav tsum them sai sai rau cov qib steel txuj ci (j {} h / j2h).
Tus nqi sib npaug: S235 / S275 series yog tus nqi qis thiab haum rau cov qauv tsis yog-tseem ceeb heev.
