Cov khoom siv dab tsi yog A479 S31803 bar?
ASTM A479 / A479M yog tus qauv tseem ceeb rau cov khoom siv stainless hlau siv hauv boilers thiab cov hlab ntsha siab. ASTM A479 S31803 stainless hlau bar Tshuag yog ua los ntawm duplex stainless hlau, feem ntau hu ua 2205 duplex stainless hlau. Nws muaj lub zog siab, zoo heev corrosion kuj (tshwj xeeb tshaj yog tiv taus chloride corrosion thiab pitting), thiab weldability zoo. Nws yog feem ntau siv nyob rau hauv tshuaj, roj thiab roj, thiab marine ib puag ncig, thiab yog haum rau tuav thiab profiles nyob rau hauv boilers thiab siab hlab ntsha. Nws cov khoom zoo ib yam li ASTM A182 F51.

GNEE yog ib tus neeg muab kev ntseeg siab ntawm stainless hlau puag ncig tuav, muab UNS S31803 / 1.4462 round bars nrog diameters feem ntau xws li Ø6 hli mus rau Ø450 hli, thiab muaj nyob rau hauv cov tshuaj annealed los yog tov annealed thiab hnub nyoog tej yam kev mob.
Txhua AISI 2205 stainless hlau puag ncig tuav yog tsim raws li ASTM A479 thiab ASTM A276 tus qauv thiab tuaj yeem muab tau nrog EN 10204 3.1 daim ntawv pov thawj.
GNEE muaj ntau yam khoom siv, xws li kub-khoov bar, forged tuav, tev bar, polished tuav, thiab txiav - mus rau - ntev tuav, kom ua tau raws li cov kev sib txawv thiab kev ua tau zoo.
Rau kev thauj mus los thiab ntim khoom, cov kab puag ncig yog kho nrog cov roj los tiv thaiv - xeb, yas qhwv, thiab ntim rau hauv seaworthy ntoo crates lossis steel strapping.
