Cov Lus Qhia Yooj Yim ntawm S275N

Kev txhais lus thiab kev tsim qauv

S275N yog qhov qis -} ally high - lub zog txheem hlau nyob hauv European txheem. Qhov kev tsim qauv yog teeb tsa raws li hauv qab no:

 

"S": Sawv rauTxheej txheem steel, qhia nws thawj qhov kev siv hauv load - cov kabmob qauv nyob thoob plaws kev tsim kho thiab tshuab raug.

"275": Sawv cev rauYam tsawg kawg nkaus zog zog ntawm 275 mpaRau cov hlau nrog cov tuab tsawg dua lossis sib npaug rau 16 hli. Tus nqi no ua kom ntseeg tau cov khoom tuaj yeem tiv taus sab nraud sab nraud sab nraud tsis pom tseeb yas deformation, muab cov txheej txheem ruaj khov.

"N": Txhais tau tias qhov kev xa khoom muaj mob liZoo li caslos yog li qub -}} kuav. Recumization rov qab kho cov qauv nplej, txhim kho cov khoom siv mechanical (piv txwv li lub zog, kev ua kom muaj zog, thiab homogen muaj kev tsim kho microstructivure.

Qauv Ua Haujlwm

S275N Adheres rauEN 10025-3: 2006Txheem, uas tswj hwm:

 

Tshuaj Muaj Tshuaj:

Qhia meej txog cov khoom tseem ceeb rau cov ntsiab lus loj (C, Si, MN, P, S) thiab Microalloy cov ntsiab lus (NB, V, los xyuas cov khoom uas xav tau.

Piv txwv li txwv:

C Tsawg dua lossis sib npaug rau 0.18%, MN: 0.45-1.60%, p / s tsawg dua lossis sib npaug rau 0.025%.

MicroalyLying ntsiab (NB, V, T, TI) tau ntxiv rau refine nplej thiab txhim kho lub zog {{} kev sib npaug sib npaug.

Cov Khoom Siv Neeg Kho Tshuab:

Paib lub zog (rov qab):

Ntau dua los yog sib npaug rau 275 mpa (tsawg dua lossis sib npaug rau 16 mm tuab); txo qis nrog tuab (piv txwv li, ntau dua lossis sib npaug rau 245 MPA rau 16-40 mm).

Lub zog tensile (RM): 410-560 MPa (sib txawv nrog tuab).

Elongation (a): Ntau dua lossis sib npaug rau 24% (tsawg dua lossis sib npaug rau 16 mm tuab), kom muaj zog.

Kev Cuam Tshuam: Loj dua los yog sib luag rau 27 J (Longitudinal) ntawm -20℃(Nco tseg

Qhov seem ntev:

Kev tswj hwm cov kev cuam tshuam rau kev sib txawv rau cov tuab, dav, thiab ntev kom ntseeg tau tias yog qhov tseeb thiab interchangability hauv fabrication.

Nto Zoo:

Txwv tsis pub cov khoom tawg tsis zoo xws li cov kab nrib pleb, hlwv, pob hluav taws, thiab suav nrog kev ua haujlwm thaum ua lossis kev pabcuam.

 

 

 

 

 

 

 

 

 

Kev sib piv nrog cov qhab nia cuam tshuam

Teem nqi	Tawm lub zog (tsawg dua los yog sib npaug rau 16 hli)	Qhov cuam tshuam kub	Qhov tseem ceeb sib txawv
S275jr	Ntau dua los yog sib npaug rau 275 mpa	+20℃(chav ua hauj sam)	Tsis muaj microalloying; Tus nqi qis tshaj.
S275J0	Ntau dua los yog sib npaug rau 275 mpa	0 Qib	Txhim kho qis qis - kub 韧性.
S275N	Ntau dua los yog sib npaug rau 275 mpa	-20 degree	Normalized rau kev nruj dua.
S275NL	Ntau dua los yog sib npaug rau 275 mpa	-50 degree	Txhim kho qis qis - kub 韧性.

Sau ntawv cia

Vuam: Siv qis - hydrogen mround electrodes (piv txwv li, e42xx series) rau kev ntseeg siab.

Kev sib sau: Txoj kev txias txias yog ua rau muaj kev tiv thaiv medormations; Kub txoj kev pom zoo kom pom zoo rau cov duab nyuaj kom tsis txhob ua haujlwm hnyav.

Ntaub: Nruab hardness tso cai rau siv cov qauv siab - ceev cov cuab yeej hlau ceev.

 

S275N cov qauv qauv thiab txhim khu kev qha ua rau nws xaiv ntau yam rau cov ntawv thov kev tsim qauv nyob hauv European Egineering.
