Qhov ntau thiab tsawg rau sm490ya / yb H-nqaj muaj suav txog qhov ntau thiab tsawg los ntawm 100000 xyoo.
Txheem: Jis g {0}} rolled steel rau welded qauv qauv
Qeb: Cov siab lub zog Tsawg Alloy Hlau (HSLA)
Cov Qib Qauv Hlau: SM490YA thiab SM490YB
SM490YA: Ntau dua cov txiaj ntsig lub zog, tsis tas yuav tsum muaj kev cuam tshuam yuav tsum muaj.
SM49 {0 yb: Ntau dua txiaj ntsig lub zog, cuam tshuam ntawm 0 degree yuav tsum tau ua.
Daim Ntawv: H-Beam (kuj muaj nyob hauv cov phaj, cov ntawv txheeb lossis lwm cov duab, tab sis H-Beach thiab cov phiaj feem ntau yog cov).
Siv: Tsim los rau Welded cov ntawv thov cov ntawv thov yuav tsum tau txhim kho lub zog thiab kav ntev.

Lub cev cov yam ntxwv ntawm H-Beams
SM490ya / yb H-nqaj yog kub dov thiab muaj cov yam ntxwv hauv qab no:
High bending tsis kam: zoo tiv thaiv dabtsi yog khoov hauv txhua cov lus qhia.
Siab thauj-cov kabmob muaj peev xwm: Qhov zoo tagnrho rau kev txhawb nqa cov khoom siv hnyav hauv cov txheej txheem.
Kev tsim kho kom ua tiav: Yooj yim sib dhos thiab txo cov kev siv tau, txo tus nqi.
Cov Ntawv Thov
SM490ya / yb H-nqaj yog dav siv nyob rau hauv cov ntawv thov kom muaj zog, Weldability zoo thiab cov qauv kev ntseeg:
Txuas hniav: Vim lawv lub zog siab, ntev ntev tsim nrog kev txhawb nqa cov nqaj hlau.
Vaj tse: Ntas rau cov tsev siab siab, cov chaw khaws khoom lag luam thiab cov chaw muaj kev lag luam.
Cov nkoj: cov qauv txheej txheem hauv nkoj.
Cov cuab yeej siv tsim khoom: Cranes, booms thiab oldellMoving machinery.
