Cov ntaub ntawv dav dav

EN 10025 S355 hlau yog European tus qauv hlau qauv, raws li EN 10025-2: 2004, cov khoom S355 tau muab faib ua 4 qib zoo tseem ceeb:
● S355JR (1.0045)
● S355J0 (1.0553)
● S355J2 (1.0577)
● S355K2 (1.0596)
Cov khoom ntawm cov hlau qauv S355 zoo dua li cov hlau S235 thiab S275 hauv kev muaj zog thiab lub zog tensile.

Qib Hlau S355 Lub Ntsiab Lus (Kev Xaiv)

Cov ntawv thiab cov lej hauv qab no piav qhia txog lub ntsiab lus ntawm qib hlau S355.
"S" yog luv rau "structural steel".
"355" yog hais txog qhov tsawg kawg nkaus ntawm cov khoom muaj zog rau cov hlau tiaj tus thiab ntev tuab ≤ 16 hli.
"JR" txhais tau hais tias lub zog cuam tshuam yog tsawg kawg 27 J ntawm chav tsev kub (20 ℃).
"J0" tuaj yeem tiv taus lub zog cuam tshuam tsawg kawg 27 J ntawm 0 ℃.
"J2" cuam tshuam nrog qhov tsawg kawg nkaus ntawm lub zog cuam tshuam yog 27 J ntawm -20 ℃.
"K2" txhais tau hais tias qhov tsawg kawg nkaus ntawm lub zog cuam tshuam yog 40 J ntawm -20 ℃.
