S355J2 thiab S355J0yog ob qho txheej txheem steel cov qhab nia hauv qab EN 10025-2 tus qauv, tab sis lawv txawv, tab sis lawv txawv ntawm lawv cov kev ua tau zoo ntawm qhov chaw sib txawv.
Ntawm no yog cov ncauj lus piav qhia:
Kev Cuam Tshuam Kev Ntsuas Kub
S355J0:
- Kev Cuam Tshuam Kub: 0 Qib (32℃F).
- Notch Kev Nyuaj Siab: Cov hlau tau sim rau nws cov kev cuam tshuam lub zog ntawm 0 degree. Qhov no txhais tau tias nws yog tsim los tswj kev nruj ntawm qhov kub no tsis muaj nkig.
S355J2:
- Kev Cuam Tshuam Kub: -20 Degree (-4 Qib F).
- Notch Kev Nyuaj Siab: Cov hlau tau sim rau kev cuam tshuam rau kev cuam tshuam lub zog ntawm-20 degree. Qhov no ua rau S355j2 haum rau cov chaw nyob hauv qab uas yuav tsum tau khaws cov tawv me me ntawm qhov chaw kub qis dua.
Daim Ntawv Thov Kom Haum
S355J0:
Haum rau cov qauv txheej txheem dav dav ntawm cov ntawv thov uas kub tau nyob ib puag ncig 0℃lossis siab dua.
S355J2:
Xav tau ntau dua rau cov huab cua txias lossis cov ntawv thov uas txias poob rau qib, xws li cov choj sab nraum zoov, txuas ntxiv, lossis cov txheej txheem hauv ib puag ncig txias.
Cov Khoom Siv Neeg Kho Tshuab
- Tos lub zog: ob qho s355j0 thiab s355j2 muaj cov khoom zoo sib xws nrog tsawg kawg nkaus muaj zog ntawm 355 MPa.
- Lub zog tensile lub zog: lub zog tensile ntawm ob qib tseem zoo sib xws.
Charpy cuam tshuam Kev Ntsuas
- S3555j0: Yuav tsum muaj kev cuam tshuam tsawg kawg ntawm 27 Joules ntawm 0 degree.
- S355J2: Yuav tsum muaj kev cuam tshuam tsawg kawg ntawm 27 Joules ntawm -20 degree.
Lub ntsiab
S3555j0 yog qhov tsim nyog rau cov ntawv thov uas qhov kub tsis poob qis dua 0 degree, ua rau nws zoo tagnrho rau huab cua huab cua me.
S3555j2 yog tsim los rau ib puag ncig txias, nrog kev ua kom zoo dua ntawm qhov kub uas tsawg li -20 degree.
Yog tias koj txoj haujlwm cuam tshuam rau qhov kub me, s355j2 yuav yog qhov kev xaiv zoo dua vim nws txoj kev nruj me ntsis hauv cov xwm txheej zoo li no.

Cov FAQ
Q: Dab tsi yog qhov txawv ntawm S355 JR. thiab S355 J2?
A: Ib qho ntxiv, cov neeg tau xav txog qhov sib txawv ntawm S355J2 thiab cov lus teb rau qhov no tuaj yeem yog qhov sib txawv ntawm ob hom hlau sib txawv.
Q: Dab tsi yog qhov txawv ntawm J2 thiab JR steel?
A: JR cov khoom siv yog feem ntau siv nyob rau hauv ib puag ncig sab hauv hos hos yog rau kev siv sab nraud. Yog tias J2 yog xav tau koj yuav tsum tsis hloov JR.
Q: Dab tsi yog s355j2 steel?
A: S355J2 yog qhov nruab nrab, cov pa roj carbon manganese uas tau yooj yim weldable thiab muaj kev cuam tshuam zoo tsis kam (tseem nyob hauv sub- xoom} xoom} xoom} xoom}. Cov ntaub ntawv no yog feem ntau muab tso rau hauv qhov tsis kho lossis cov xwm txheej qub. Tshuab ntawm cov khoom no zoo ib yam li cov hlau me me.
Q: S35JT0 yog dab tsi?
A: Cov lus piav qhia. S355jo yog lub tensile nruab nrab, cov pa roj carbon manganese uas tau yooj yim weldable thiab muaj kev cuam tshuam zoo tsis kam. Cov ntaub ntawv no yog feem ntau muab tso rau hauv qhov tsis kho lossis cov xwm txheej qub. Tshuab ntawm cov khoom no zoo ib yam li cov hlau me me.
Q: Dab tsi yog s355j0 cov khoom sib npaug rau?
A: ASTM A572 Qib 50
S3555j0 yog sib npaug rau ntau qeb steel hauv as772, thiab GIS SM490, thiab GIS SM490, thiab GIS SM490, thiab GIF / T Q345B, nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov thiab cheeb tsam cov qauv.
Q: Dab tsi yog cov nyiaj tawm los lub zog ntawm s355j0 steel?
A: 355 MPa
Qib S35555j0 muaj tsawg kawg yog lub zog muaj zog ntawm 355 mpa
