Mu duplex zitsulo zosapanga dzimbiri (DSS), gawo la austenite ndi gawo la ferrite limakhala pafupifupi theka la dongosolo lolimba la yankho, ndipo lili ndi mawonekedwe amitundu iwiri. Sikuti amangokhala ndi makhalidwe a ferritic zosapanga dzimbiri zitsulo, monga lalikulu matenthedwe madutsidwe, yaing'ono liniya kufutukula koyefike, kukana pitting dzimbiri ndi mng'oma dzimbiri, ndi chloride nkhawa dzimbiri, komanso ali kulimba wabwino, otsika Chimaona kutentha kutentha ndi kukana intergranular dzimbiri. zitsulo zosapanga dzimbiri za austenitic. Ndi ntchito yabwino komanso zabwino zina, imagwiritsidwa ntchito kwambiri mu petrochemical, kusindikiza ndi utoto, uinjiniya wamadzi, mafakitale azakudya ndi mafakitale opanga mapepala.
Ndi chizolowezi chokulitsa kukula kwa zida zamakono zamafakitale ndikuchepetsa mtengo wopangira, zigawo zina zazikulu zimapangidwa ndikukuta zigawo zaduplex zosapanga dzimbiri zosagwira dzimbiri pazitsulo zazitsulo zotsika.
Njira ya Strip electroslag surfacing process imagwiritsidwa ntchito kwambiri popanga chifukwa chokhazikika chowotcherera, makina apamwamba kwambiri, komanso kupanga bwino.
Table 1 GDS-2209 riboni kapangidwe
Table 2 GDS-2209&GXS-E330 wayika zitsulo zikuchokera
Table 3 GDS-2209&GXS-E330 kupindika ndi kukana dzimbiri

Chithunzi cha ASTM A923C Intergranular Corrosion 4T180 chopindika chakumbali
Kugwiritsa ntchito kumunda kwa mizere yowotcherera
Zopangira zitsulo zosapanga dzimbiri zosapanga dzimbiri zopangidwa ndi kampani yathu (mizere ya GDS-2209 yokhala ndi GXS-E330 flux) imakhala ndi ntchito yabwino kwambiri yowotcherera komanso zinthu zakuthupi ndi zamankhwala, zomwe zimatha kukwaniritsa zofunikira pakupanga ndi kupanga. Takulandilani kuti mufunse ndikugula.
