Cov Lus Qhia Dav Dav

EN 10025 S355 B355 STEEL yog European Cov Qauv Hlau Txheej Txheem Hlau, (2004, Cov Khoom Siv S355 tau muab faib ua 4 lub ntsiab zoo qib:
● S355jr (1.0045)
S355J0 (1.0553)
● S355J2 (1.0577)
● S355K2 (1.0596)
Cov yam ntxwv ntawm cov hlau txheem steel s355 zoo dua li cov hlau S235 thiab S275 nyob rau lub zog zog thiab lub zog tensile.

Qeb qib S355 lub ntsiab lus (kev tsim qauv)

Cov tsiaj ntawv thiab xov tooj hauv qab no piav qhia cov qauv steel s355 lub ntsiab lus.
"S" yog luv rau "cov qauv hlau".
"355" Yog hais txog lub minumum paib muaj zog muaj nqis rau lub tiaj thiab ntev hlau tuab ≤ 16 hli.
"Jr" txhais tau tias muaj kev cuam tshuam lub zog muaj nqis 27 j ntawm chav kub (20 ℃).
"J0" tuaj yeem tiv thaiv qhov kev cuam tshuam lub zog tsawg kawg 27 J ntawm 0 ℃.
"J2" ntsig txog lub minumum yam cuam tshuam lub zog tus nqi yog 27 J ntawm -20 ℃.
"K2" Hais txog lub minumum cuam tshuam lub zog muaj txiaj ntsig tus nqi yog 40 J ntawm -20 ℃.
