ASTM A249 Stainless Hlau 347 Boiler Tubes yog austenitic stainless acid-resistant steel uas muaj cov ntsiab lus xws li chromium, npib tsib xee thiab niobium, uas muaj qhov kub thiab txias tsis kam thiab intergranular corrosion kuj.
Lub melting point ntau ntawm ASTM A249 TP347 stainless hlau raj yog 1398-1427 degree, thiab qhov ceev yog 7.9g / cm³. Nws qhov tshwj xeeb kub muaj peev xwm yog 500J / (kg·K), thiab cov elastic modulus txawv ntawm qhov kub thiab txias, piv txwv li, 196GPa ntawm 20 degree thiab 167Gpa ntawm 600 degree.
ASTM A249 TP347 stainless hlau round raj yog dav siv nyob rau hauv aviation, petrochemical, zaub mov, papermaking thiab lwm yam lag luam thiab ua hauj lwm nyob rau hauv tej yam kev mob uas kub tsis tshaj 850 degree.
