EN 10219 S275J2H Hollow Seem

En 10219 S275J2h yog cov qauv tsis-alloy

Cov neeg kho tshuab ntawm S275JRH hlau qib yog qhov tseem ceeb rau nws cov ntawv thov cov txheej txheem:

• Paib lub zog: Tsawg kawg 275 mpa
• Lub zog tensile: {430-580 mpa
• Elongation (%): 23% rau thickness tsawg dua los yog sib npaug rau 16 hli, txo qis rau cov tuab tuab
• Kev Cuam Tshuam Lub Zog: 27 j ntawm chav kub (20 degree)

S355 muaj qhov muaj txiaj ntsig ntau dua thiab tensile lub zog piv rau S235 thiab S275, qhia txog lub peev xwm ntau dua thiab nqa khoom muaj peev xwm. S355 kuj tseem muaj qis dua kev nrhiav tau rau S235, xav txog kev lag luam tawm ntawm lub zog thiab kev sib tw.

Phosphorus (p)	0.035
Sulphur (s)	0.035

 Nyem qhov no yog dab tsi yog EN 10219 tus qauv

 

S355 tau qis dua phosphorus thiab cov Sulphur cov ntsiab lus piv rau S235 thiab S275, uas tuaj yeem pab txhawb rau Weldability zoo dua thiab tawv. Cov ntsiab lus carbon kuj tseem me ntsis nyob rau hauv S355 me me, uas feem ntau cov txiaj ntsig tau muaj zog dua.

S275JRH yog siv nyob rau hauv ntau cov ntawv thov kev thov vim nws cov khoom siv sib npaug thiab cov qauv zoo:

• Txheej Txheem Hlau Yeeb Nkab: Feem ntau yog siv rau cov txheej txheem thiab tshuab ntaus kho txhua yam uas zoo weldability thiab muaj peev xwm yog xav tau.
• Kev tsa tsev: Siv hauv kev tsim kho ntawm cov tsev, choj, thiab lwm yam phiaj xwm lwm txoj haujlwm.
• Engineering tej yaam num: Ua haujlwm hauv cov phiaj xwm subway thiab lwm cov haujlwm engineering uas yuav tsum tau cov qauv hlau.

S355 muaj lub zog siab dua thiab kev nruj sib piv piv rau S235 thiab S275, ua rau nws tau txais kev siv ntau dua, tshwj xeeb hauv cov huab cua txias dua. S235 feem ntau yog siv rau cov ntawv thov tsawg dua uas tus nqi yog ib qho yog qhov txiaj ntsig, thaum S275 muab qhov sib npaug ntawm lub zog thiab ductility rau ntau cov ntawv thov.

S275JRH muaj ob peb qhov zoo uas ua rau nws haum rau ntau cov ntawv thov:

• Cov Khoom Siv Zoo Tshaj Plaws: S275JRH muaj lub siab ua kom muaj zog thiab tensile lub zog, muab kev ua tau zoo hauv ntau qhov kev siv engineering.
• Yooj yim ntawm kev ua thiab vuam: S275JRH paub txog nws txoj haujlwm zoo thiab weldability, kev ua tiav kev ua thiab sib dhos ntawm-xaib.
• Nqi zog-ua hauj lwm: Raws li cov hlau tsis-alloy, S275JRH feem ntau tau siv tus nqi ntau dua rau alloy hlau thaum tseem muab lub zog zoo thiab lub zog zoo.

S275J2H yog ib qib steel tsis-alloy steel nrog cov khoom siv hluav taws xob zoo, ua kom haum cov qauv txheej txheem thiab cov engineering, tshwj xeeb yog cov kev xav tau tsawg-kub.
