Seamless alloy steel hlab thiab cov kav dej, tshwj xeeb tshaj yog tus qauv ASTM A213, tau dav siv hauv boilers, heat exchangers, high-pressure units, superheaters thiab reheaters. Vim lub hardness thiab mechanical zog ntawm seamless alloy steel kav, lawv tsim nyog rau qhov kub thiab txias ib puag ncig. ASTM A213 tus qauv rau seamless ferritic thiab austenitic alloy steel boiler, superheater thiab tshav kub exchanger raj.
Ntxiv nrog rau cov yeeb nkab steel hlau, ASTM A213 tseem npog cov yeeb nkab steel hlau, uas tseem siv dav hauv boilers, kub exchangers, thiab condensers.
Tsis tas li ntawd, lwm cov kav dej xws li ASTM A519 SAE4130, 40Cr, 20Cr kuj yog peb cov khoom tsis tu ncua.
