High Carbon steels SAW waldi waya F7A/P4-ECG da waldi juzu'in walda ƙirƙira haɗin gwiwa
An yi amfani da shi don tasirin -60C da ake buƙata yanayi, gabaɗaya ana amfani da shi don ginin jirgi, bututun mai, walƙiya jirgin ruwa.
Menene halaye?
●The karfe foda irin submerged baka waldi waya na 480MPa sa high ƙarfi karfe ne welded da GXL-121 juyi. Konewar baka ya tsaya tsayin daka, kawar da slag abu ne mai sauki, kuma hanyar walda ta kafa tana da kyau.
●Ƙarfin weld ɗin yana da kyawawan kaddarorin inji, ƙananan abun ciki na P da S, da kyakkyawan aiki mai ƙarancin zafin jiki.
