ASTM A249 TP 304L stainless hlau welded yeeb nkab yog ua los ntawm 304L stainless hlau khoom. 304L stainless hlau yog ib qho qis-carbon version ntawm 18-8 stainless hlau thiab muaj zoo corrosion kuj thiab processability.
ASTM A249 TP 304L qhia qhov yuav tsum tau ua rau cov yeeb nkab loj, phab ntsa tuab, ntev thiab qhov sib txawv ntawm qhov tso cai. Cov kev qhia tshwj xeeb no feem ntau yog los xyuas kom meej qhov tsim nyog thiab kev ntseeg siab ntawm cov yeeb nkab.
ASTM A249 TP 304L yuav tsum tau vuam txheej txheem rau ntau lawm. Cov txheej txheem welding feem ntau suav nrog TIG (argon arc vuam), MIG (hlau inert gas welding), tsis kam vuam, thiab lwm yam.
ASTM A249 TP 304L stainless hlau welded yeeb nkab feem ntau yog siv rau hauv kev lag luam, tshuaj, khoom noj khoom haus thiab lwm yam kev lag luam, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas yuav tsum tau muaj kev tiv thaiv corrosion.
