S275J0 steel ntawv yog hom qauv hlau ua haujlwm hauv qab steel qauv hauv 10025-2275j0 steel hlau yog siv rau cov vaj tse hlau qauv, thav duab thiab lwm cov hlau lub cev.
S275J0 Steel hlau phaj, J0 yog rau qhov kub tsawg tshaj cuam tshuam rau hauv xoom cenigree. Nyob rau hauv Suav steel txheem gb, cov no tseem yog ib qib hlau yog tib yam li S275J0, nws yog Q275C.
Ob lub steel cov qauv muaj cov tshuaj sib xyaw ua ke zoo sib xws thiab cov cuab yeej siv tshuab.xinsteel Industrial tshwj xeeb hauv Kub Rolled steel phaj s275j0 nyob rau hauv Suav teb ntau xyoo.

EN10025-2 S275JR Hlau Daim Hlau tau dav siv hauv kev tsim kho choj, txoj kev loj thiab muaj kev sib xyaw ua ke, kev sib xyaw ua ke, thiab kev sib txawv.
Hauv cov choj, cov phiaj hlau no feem ntau siv rau cov tsiaj, kab hlau, cov paib hla, muab cov kabmob sib luag thiab ntev}} hom kev ruaj khov. Hauv cov phiaj xwm kev loj, lawv tau thov rau hauv cov neeg zov me nyuam, kev thaiv kev nyab xeeb, thiab kev txhawb nqa tsis tu ncua nyob rau hauv kev ntxhov siab thiab kev ntxhov siab ib puag ncig.
Ntxiv nrog rau cov phiaj xwm kev tsim kho, S275JR daim hlau muab rau hauv cov tuam tsev muaj kev lag luam, thiab tso tsheb hlau luam, kev ua tau zoo, thiab weldability kev ua haujlwm, thiab weldability kev ua haujlwm, thiab weldability kev ua haujlwm, thiab weldability kev ua haujlwm, thiab weldability kev ua haujlwm, thiab weldability kev ua haujlwm, thiab weldability kev ua haujlwm, thiab weldability kev ua haujlwm, thiab weldability kev ua haujlwm, thiab weldability kev ua haujlwm, thiab weldability kev ua haujlwm, thiab weldability kev ua haujlwm, thiab weldability ua tau zoo. Cov hlau cov khoom tso cai rau kev ua kom muaj txiaj ntsig zoo ntawm cov txheej txheem nyuaj, ua kom haum rau ob qho loj- nplai thiab kev cai engineering cov haujlwm.
Raws li EN 10025 - 2: 2004, s275jr tau muab cov khoom siv muaj zog, kev tsim kom muaj zog, kev tsim kho kom muaj zog, thiab 10025-2, 2004). Nws cov kev siv thoob plaws hauv kev tsim kho pej xeem thiab kev lag luam ua rau nws muaj kev ntseeg siab, versatility, thiab nqi zog.
