Dab tsi yog ASTM A249?
ASTM A249 yog cov qauv kev qhia rau Welded Austenitic steel leeg siv hauv boilers, superheaters, kev hloov cua sov, thiab cov condensers tshav kub. Cov tub tsho uas tau them los ntawm daim ntawv qhia kev tshwj xeeb no yuav tsum welded, ces ua haujlwm txias kom ua tiav cov khoom uas xav tau, thiab thaum kawg kho nws cov microstructure.
