High-strength boiler steel phaj Q370R yuav tsum tau normalized thiab kub-kho thaum dov. Tag nrho cov hlab ntsha steel phaj yuav tsum tau kuaj xyuas ultrasonically.
GB713 Q370R siab txog ntsha thiab boiler steel phaj yog siv rau cov hlab ntsha siab, boilers, tso tsheb hlau luam thiab kub exchangers nyob rau hauv cov roj thiab roj tej yaam num.
