Mild Steel Qauv H Bean SM490
SM490 Kub Rolled Steel yog ib tug qauv steel txheej txheem tshwj xeeb los ntawm Japanese muaj cov khoom siv Japanese (JIS G3106), "SM" sawv tsawg tensile lub zog ntawm 490 mpa.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm SM49 0 cov qauv hlau qauv suav nrog: carbon (c) tsawg dua lossis sib npaug}. 26%; Silicon (si) tsawg dua lossis sib npaug rau 0. 55%; Manganese (mn) tsawg dua lossis sib npaug rau 1.6 {9 {9}}%; Phosphorus (p) tsawg dua lossis sib npaug rau 0.035%; Sulfur (s) tsawg dua los yog sib npaug rau 0.035%, uas ua tib zoo sib npaug kom ntseeg tau cov khoom siv zoo thiab weldability.
SM490 Hlau muaj cov khoom siv medevical tshuab, tensile lub zog ntau dua los yog sib luag rau 490 mpa; paib lub zog ntau dua los yog sib npaug rau 235 MPa; elongation ntau dua los yog sib npaug rau 22% (tuab <50mm), uas qhia txog lub zog siab thiab kev ducility siab.
SM490 H-Beams tuaj yeem ua tau yooj yim siv cov qauv ib txwm muaj lub zog xws li SS400 qib, uas muaj kev ua tau zoo dua hauv cov ntawv thov kev hnyav.
Txhawm rau txhim kho corrosion tsis kam lossis txhim kho cov tsos, GNEE tuaj yeem siv cov khoom siv tog tog xws li pleev xim, galvanizing lossis hmoov zoo li nqaj. Cov kev kho no yog qhov tshwj xeeb rau sab nraum zoov daim ntawv thov, qhov twg cov hlau yuav kis tau cov mob hnyav.
