GNEE, ua tus kws tshaj lij ntawm ASTM A358 stainless hlau kav, xa tawm 20 tons ntawm stainless hlau kav mus rau txawv teb chaws kev lag luam txhua xyoo. ASME SA358 321H stainless hlau EFW yeeb nkab yog lub zog muaj zog, siab kub resistant austenitic stainless hlau yeeb nkab haum rau ntau qhov chaw kub thiab corrosive. Nws tuaj yeem tswj xyuas cov khoom zoo ntawm qhov kub txog li 870 degree thiab tshwj xeeb tshaj yog haum rau cov ntawv thov hauv qhov kub thiab txias.
ASME SA358 321H EFW stainless hlau yeeb nkab muab los ntawm GNEE ntxiv titanium rau chromium-nickel stainless hlau los tiv thaiv intergranular corrosion, tshwj xeeb tshaj yog thaum vuam, los tiv thaiv intergranular corrosion nyob rau hauv tshav kub-cuam tshuam cheeb tsam tom qab vuam. Nws yog feem ntau siv hauv kev tsim cov yeeb nkab steel thiab cov yeeb nkab fittings xws li boiler superheaters, tshav kub exchangers, condensers, catalytic tubes, cracking tube units, thiab lwm yam.
