Khoom taw qhia
ASTM A572 Steel Lub kaum sab xis

ASTM A572 steel lub kaum sab xis yog lwm qhov muaj zog, qis-alloy (HSLA) columbium-vanadium steel seem. Raws li qhov me me ntawm columbium & vanadium alloy cov ntsiab lus, kub dov A572 steel lub kaum sab xis muaj cov khoom zoo dua li carbon steel A36. Ua ntej, A572 muaj lub zog ntau dua li A36 zoo li lub zog tawm los thiab lub zog tensile. Qhov thib ob, nws yog ib qho yooj yim rau weld, daim ntawv thiab tshuab.

A572 siab zog steel kaum

Galvanized & Pre-lacquered steel kaum
A572 steel lub kaum sab xis muaj kev siv dav vim qhov sib piv siab ntawm lub zog rau qhov hnyav. Vim tias nws tsis muaj cov ntsiab lus tooj liab uas muaj txiaj ntsig zoo rau corrosive, A572 cov qauv hlau cov ces kaum feem ntau yog kub-dip galvanized lossis pre-lacquered. Cov xim rau painting yog nyob ntawm koj qhov kev thov.

A572 steel lub kaum sab xis piav qhia:

  • Hlau qib: A572.
  • Kev qhia: ASTM A572

    • Loj: 20 × 20 - 200 × 200.
    • Thickness: 3-22 hli.
    • Ntev: 6 m, 9 m, 12 m los yog raws li koj qhov kev thov.
  • Lub kaum sab xis tsis sib xws:
    • Loj: 20 × 30 txog 90 × 250.
    • Thickness: 3-15 hli.
    • Ntev: 6 m, 9 m, 12 m los yog raws li koj qhov kev thov.

Lus Cim: Qhov tshwj xeeb lub kaum sab xis steel qhov ntau thiab tsawg yog muaj yog tias koj qhov kev txiav txim kom muaj nuj nqis tshaj qhov tsawg kawg nkaus.

A572 steel lub kaum ntse ntse nta & cov txiaj ntsig:

  • Lub zog zoo heev rau qhov hnyav piv rau kev siv cov qauv uas qhov hnyav yog qhov teeb meem.
  • Muaj zog dua me ntsis carbon A36 steel lub kaum sab xis.
  • A572-50 Muab rau 50 ksi yam tsawg yield zog thiab 65 ksi tensile zog.
  • Zoo tagnrho rau cov tsev steel thiab cov qauv uas xav tau lub zog ntxiv.
