COMPOSITION OF FLUX FOR WELDING AND HARD FACING BY WIRE AND AUSTENITE STEEL TAPE Russian patent published in 2014 - IPC B23K35/362 B23K9/18

Abstract RU 2530107 C1

FIELD: metallurgy.

SUBSTANCE: fused flux contains the components at following ratio, wt. %: SiO₂9-15, CaO 19-31, Al₂O₃ 28-34, CaF₂ 29-33, Fe₂O₃ 0.005-1.000, MgO 0.005-2.000, MnO 0.01-1.000. Note here that the following relationship should be satisfied: (CaO/2+5MgO+30MnO+2.6Fe₂O₃)/SiO₂≥1 and (SiO₂-8)⁴/(31F₂O₃+10MnO)≤1000. Welding flux can be used with austenite welding surfacing materials with decreased content of carbon. Note here that it ensures higher resistance of added metal to blistering by thermal ageing.

EFFECT: longer life of reactor plants.
