Q345R Hlau Phaj: Qhov kawg Siab Siab Cov Khoom Siv
Txais tos rau YUXIN Group- tus thawj coj tau ntawv pov thawj xa khoom thiab xa tawm ntawm siab -kev ua tau zooQ345R steel phajhauv Suav teb. Raws li cov khoom xav tau rau cov hlab ntsha siab, boilers, thiab cov khoom siv petrochemical, peb cov Q345R daim hlau muab cov weldability zoo dua, siab tensile lub zog, thiab zoo heev low - kub cuam tshuam toughness.
Q345R Steel Phaj yog dab tsi?
Q345Ryog qib tshwj xeeb ntawm boiler thiab siab hlab ntsha steel raws li Suav StandardGB713. Lub "R" txhais tau tias "Lub Nkoj Siab" (Rongqi). Nws yog ib qho qis- alloy steel paub txog nws qhov tshwj xeeb ua haujlwm rau qhov kub thiab txias thiab siab - qhov chaw siab.
Thaum siv dav raws li tus nqi - siv tau zoo rauASME SA516 Gr70, Q345R muaj qhov tshwj xeeb zoo hauv kev tawm dag zog thiab kev tiv thaiv corrosion rau cov khoom siv thermal.
Cov qhab nia sib npaug tseem ceeb:
