S275J2H yog qhov tsis - almoy}} {}}}), xws li kav dej, yas, thiab cov seem, thiab cov ntu hollow. Qhov "H"] Suffix qhia tias nws tau muab rau raws li qhov yuav tsum tau ua rau seem ntu. Cov hlau no tau sib txawv hauv European cov qauv en 10210-1 thiab tau pom dav rau nws zoo ua ke muaj zog, weldability, thiab kev muaj zog, thiab kev muaj zog, thiab tawv.
Kev tsim qauv "S275J2H" muab cov ntaub ntawv tseem ceeb txog cov khoom siv:
* ** S ** Sawv ntsug rau "qauv" hlau.
* ** ** ** ** ** THEM NYEEM Qhov no yog kev ntsuas qhov ntsuas ntawm nws cov thauj khoom {{}} cov kabmob muaj peev xwm.
* ** J2 ** Yog hais tias yog ** kev cuam tshuam cov tawv tawv ** kev faib tawm. Lub "J2" cov cim qhia tias cov hlau tau raug sim rau cov khoom siv hluav taws xob thiab cov neeg muaj kev nyab xeeb hauv cov khoom siv pa taws thiab muaj kev nyab xeeb rau sab nraud.
* ** H ** Tshaj tawm nws yog npaj rau ** HOLLOW ** SEEM.
** Cov yam ntxwv tseem ceeb thiab cov txiaj ntsig: **
1. ** Nrog cov ntaub ntawv tshwj xeeb, nws muaj lub zog tsim nyog, nws tsim nyog rau cov khoom siv dav dav {{2 {2 2}} belks} kev muag khoom.
2. ** Kev siv tshuaj lom neeg zoo heev: ** Cov tshuaj lom neeg muaj pes tsawg leeg muaj ntau yam kev ua haujlwm (zoo li khoov cov txheej txheem) tsis muaj qhov txaus ntshai ntawm cov khoom tawg lossis poob ntawm cov khoom. Qhov no pab tau yooj yim fabrication thiab ntawm - chaw tsim kho.
3. ** Kev sam hwm ua kom nruj: ** Lub J2 xav tau rau kev muaj zog ntawm cov kev xaiv kub tsis txaus ntseeg, xws li txuas ntxiv huab cua, thiab cov vaj tse sab nraum zoov nyob rau hauv cov cheeb tsam ntsuas.
** Cov Ntawv Thov Xyuas Feem: **
S275J2h steel kav yog ntau yam siv nyob rau hauv kev tsim kho thiab engineering cov hauj lwm rau:
* Cov qauv txheej txheem ua haujlwm rau cov tuam tsev thiab chaw ua haujlwm.
* Mechanical thiab nroj tsuag engineering qauv.
* Cov kab ntawv txhawb nqa thiab trusses.
* Cov ntawv thov architectural, suav nrog cov qauv raug pom zoo uas yog qhov tseem ceeb.
* Ntau lub hom phiaj engoressering
Hauv cov ntsiab lus, S275J2H cov yeeb nkab steel yog ib qho ntau yam, siab} Cov khoom muaj zog, ua rau nws xaiv qhov kev tsim kho tshiab niaj hnub no.
