Q355B Kub Rolled ERW Rectangular Steel Pipes

Q355B yog hom qis-alloy high-strength steel nrog cov ntsiab lus carbon xws li 0.17% mus rau 0.25%, ua rau nws muaj cov pa roj carbon ntau. Nws cov yam ntxwv tseem ceeb tshaj plaws yog nws lub zog siab, ua rau nws tiv taus cov khoom loj. Tsis tas li ntawd, Q355B low-alloy high-strength steel kuj muaj cov yas zoo thiab cuam tshuam tsis kam. Txawm tias nyob rau hauv qhov kub thiab txias, nws tuaj yeem tiv thaiv nkig tawg thaum raug cuam tshuam. Q355B cov kav dej sib npaug ua los ntawm cov hlau tsis tshua muaj siab-lub zog no ua rau muaj kev ua haujlwm siab, ua rau lawv tsim nyog rau cov qauv siv hauv kev tsim kho.
