321 chitsulo chosapanga dzimbiri 8 * 1 mm chopindika chubu
Aloyi 347H ndi chitsulo chokhazikika, cha austenitic, chromium chokhala ndi columbium chomwe chimalola kuthetsa mpweya wa carbide, ndipo, chifukwa chake, intergranualr corrosion.Aloyi 347 imakhazikika ndi zowonjezera za chromium ndi tantalum ndipo imapereka zinthu zokwera kwambiri komanso zosokoneza kwambiri kuposa aloyi 304 ndi 304L zomwe zingagwiritsidwenso ntchito powonekera komwe kukhudzidwa ndi dzimbiri la intergranualr ndizodetsa nkhawa.Kuwonjezera kwa columbium kumapangitsanso Aloyi 347 kukhala ndi kukana kwambiri kwa dzimbiri, ngakhale kupambana kwa alloy 321. 347H ndi mawonekedwe apamwamba a carbon a Alloy 347 ndipo amasonyeza kutentha kwapamwamba ndi kukwawa.Zolemba za Haosteel Stainless tsopano zikuphatikiza Alloy 347/347H (UNS S34700/S34709) mu pepala, koyilo yamapepala, mbale, mipiringidzo yozungulira, mipiringidzo yosanja yopangidwa ndi tubular.
