Cov Khoom Siv
Q345B mild steel plate, produced under the GB/T 1591 standard, is a low-alloy, high-strength structural steel widely used in construction, machinery, transportation, and energy industries.
Nrog cov txiaj ntsig lub zog ntawm 345 MPa thiab tensile lub zog xws li ntawm 470 txog 630 MPa, thiab weldility, ua rau nws yog feem ntau ntawm cov qauv tsim qauv muaj.
Kev tsim kho thiab vaj tse
Q345B daim phiaj yog qhov siv tau zoo nyob rau hauv high -}}}}} {}}}}} lub zog ruaj khov yog qhov yuav tsum tau ua. Cov hlau lub zog zoo dua - {{6} Txoj kev siv nyhav ntxiv thaum tuav cov nqi kev ncaj ncees.
Cov cuab yeej hnyav thiab Machinery
Nyob rau hauv lub tshuab cector, Q345B steel phaj yog siv nyob rau hauv crane booms, thiab excavator caj ces vim nws cov kev cuam tshuam zoo heev thiab muaj peev xwm tiv thaiv kev ntxhov siab ntau. Cov hlau tswj hwm kev ntseeg ruaj khov txawm tias ntawm sub-}}} illational kev nyab xeeb, ua haujlwm kom muaj kev nyab xeeb hauv kev xav tau ib puag ncig.
Tsheb thauj mus los thiab txua nkoj
Q345B tseem yog cov khoom siv uas xav tau rau tsheb chassis, tsheb nqaj hlau, thiab nkoj hulls. Nws cov formability zoo thiab weldability ua rau nws tsim nyog rau kev muab cov qauv loj uas yuav tsum muaj qhov xav tau ua ntej thiab kav ntev.
Zog thiab Offshore Tej Yaam Num
Cov khoom ua tau zoo nyob rau hauv cov roj platform, cua tshuab raj, thiab cov hlab ntsha siab, qhov twg ob lub zog thiab kev tawm tsam kom qaug zog yog qhov tseem ceeb. Tus Hlau Micro -}} alloused compoated muab kev txhim kho corrosion thiab hnav tsis kam nyob rau hauv ib puag ncig marine lossis chaw ib puag ncig.
