S355 S355J2 S355J2+N channel beam
S355NL yog cov hlau tsis zoo (cov hlau zoo) hauv EN 10025-3: 2004 tus qauv. Nws lub zog tawm los thiab lub zog tensile sib haum rau kuv lub teb chaws Q345 qis alloy hlau. NL yuav tsum tau nqus cov kev cuam tshuam nyob rau hauv qhov kub thiab txias ib puag ncig ntawm rho tawm 50 degrees. Kev xeem ua haujlwm · thiab qhov cuam tshuam tus nqi tsis tsawg dua 27J.
S355J2 yog ib hom ntawm European tus qauv sib npaug rau lub teb chaws tus qauv Q345D. Nws yog ib qho qis-alloy high-strength structural steel. Vim tias nws qhov kev cuam tshuam zoo toughness thiab vuam kev ua tau zoo, qib steel phaj no tau siv dav hauv ntau yam lag luam.
Thawj S ntawm S355J2+N steel yog carbon steel structural steel, thiab 355 qab nws txhais tau hais tias qhov tsawg kawg nkaus yield zog ntawm chav tsev kub yog 355Mpa. J2 xav tau -20 degree cuam tshuam. Raws li rau lub + N qab nws, nws txhais tau tias sib npaug rau normalizing dov, tsis tas normalizing. Nws tsuas yog ib txoj hauv kev rau npe cov qib steel hauv tus qauv.
