S275JR steel phaj

Nws yog ib hom European txheem high-zoo carbon structural steel phaj. S275JR steel phaj yog hom zoo tib yam carbon structural steel phaj. Piv nrog cov pa roj carbon zoo, nws muaj kev txwv dav dua ntawm cov ntsiab lus carbon, kev ua haujlwm ntau, thiab cov ntsiab lus ntawm phosphorus, sulfur thiab lwm yam khoom seem.

European txheem S275JR carbon steel phaj zoo ib yam li cov qib steel teev nyob rau hauv GB/T 700 thiab GB/T 1591. Nws kuj yog ib tug carbon structural steel thiab tsawg alloy structural steel rau engineering thiab structural hom phiaj. Nws feem ntau yog xa tawm yam tsis muaj kev kho cua sov. Qhov tseeb, S185 yog sib npaug rau Q195; S235 thiab S275 yog sib npaug rau kuv lub teb chaws Q235 thiab Q275; S355 yog sib npaug rau kuv lub teb chaws Q345. Tsuas yog S185, kev ntsuas hluav taws xob cuam tshuam ntawm 20 degree, 0 degree thiab -20 degree yuav tsum tau.

peculiarity

 

1. Lub zog siab: Lub zog tawm ntawm S275JR steel phaj yog ntau dua li cov pa roj carbon zoo tib yam, uas tuaj yeem ua tau raws li ntau yam ntawm cov khoom hnyav thiab lub zog siab ntawm qhov chaw ua haujlwm.
2. Zoo weldability: steel phaj nyob rau hauv cov txheej txheem vuam, qhov vuam zoo yog siab, tsis yooj yim rau kev tsim cov kab nrib pleb thiab lwm yam tsis xws luag, kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov qauv vuam.
3. Zoo plasticity: S275JR steel phaj muaj zoo plasticity thiab toughness, uas muaj peev xwm tswj tau zoo deformation muaj peev xwm thaum bearing cuam tshuam load thiab txo txoj kev pheej hmoo ntawm puas.
4. Corrosion kuj: Los ntawm qhov tsim nyog alloying ntsiab piv thiab cov txheej txheem kev kho cua sov, S275JR steel phaj muaj qee qhov kev tiv thaiv corrosion, thiab tuaj yeem tiv taus qee yam tshuaj corrosion thiab electrochemical corrosion.
