S355J2 Steel H Profile Customizable Loj

S355J2 yog European tus qauv qib sib npaug rau lub teb chaws tus qauv Q355D. 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, lub hom phaj steel no tau siv dav hauv ntau yam lag luam. S355J2 yog suav nrog ECISS/TC10 "Structural Steel Grades and Quality" Technical Committee.

S355J2 steel H profile khoom qhia:

S355J2: low-alloy high-strength structural steel Q345 S355J2 yog roughly sib npaug rau GB's Q345D S355J2, J2 txhais tau hais tias lub xeev xa khoom yog normalized, thiab lub zog cuam tshuam ntawm -20 degree yog 27J.
