Gnee Steel ua tib zoo tshawb nrhiav thiab kev sim los muab cov khoom lag luam zoo rau kev ua lag luam. Thaum nws los ua cov khoom lag luam, peb yog cov kws tshaj lij. Peb faib, muab, thiab tsim khoom ntau yam, nrog rau cov kav dej thiab cov raj, cov hlua khi, coils, cov ntawv txheeb, thiab daim hlau, tag nrho nrog kev lag luam-tus qauv nta thiab cov ntsiab lus.
Peb cov khoom tau tsim kom ntev thiab ua tau raws li qhov xav tau, thiab peb muab cov nqi sib tw rau cov neeg yuav khoom. Lawv yog ua los ntawm chromium-nickel austenitic cov khoom uas muaj oxidation tsis kam thiab muaj ntau yam zoo, xws li tsis kam mus corrosion, creep, thiab kub kub. Peb stainless hlau 309 cov kav dej thiab cov raj muaj qhov zoo tshaj plaws corrosion kuj vim lawv cov hlau alloy siab. Lawv tuaj yeem siv tau rau hauv qhov chaw kub lossis txias heev ua tsaug rau lawv cov cua sov.
Stainless hlau 309 feem ntau yog siv rau hauv cov cua kub, nws pib tso cov khoom, boiler baffles, tshav kub exchangers, refineries, thiab tshuaj ua nyob rau hauv maritime industries, desalination nroj tsuag, chiv, thiab lwm yam industries. Cov kav dej thiab cov raj no yog tsim los ntawm cov khoom siv zoo tshaj plaws, uas tso cai rau lawv los ua cov txheej txheem ua kom tiav. Peb qhov tseem ceeb tshaj plaws yog kev txaus siab rau cov neeg siv khoom, thiab peb pab neeg muaj peev xwm thiab muaj siab ua kom ntseeg tau tias peb cov khoom pab peb cov neeg siv khoom zoo.
309 Stainless Hlau Yeeb Nkab Alloy 309/309S (UNS S30900 / S30908) austenitic stainless hlau feem ntau yog siv rau kev siv kub siab. Nws cov ntsiab lus siab chromium thiab npib tsib xee muab piv rau corrosion kuj, superior tiv thaiv oxidation, thiab khaws cia ntawm ib feem loj ntawm chav tsev kub lub zog tshaj cov hom austenitic Alloy 304.
