WIRE INCLUDING FLUX FOR Cu-Ni-Ti BASE HIGH ATMOSPHERIC CORROSION RESISTANT STEEL

摘要

PROBLEM TO BE SOLVED: To provide a wire including flux for gas shield are welding which is suitable to the welding of Cu-Ni base seashore atmosphere corrosion resistant steel and can be applied to the whole posture welding and obtains good welding workability and gives, to the welded metal, the corrosion resistance to flying sea salt grain without damaging the corrosion resistance of a base material. ;SOLUTION: In the wire including the flux used in the case of executing the gas shield arc welding to the Cu-Ni-Ti base high atmosphere corrosion resistant steel material, the wire composition, to the total weight of the wire, is composed, of by wt.%, 3.5-8% TiO2, 0.03-0.15% C, 0.1-1% Si, 0.8-3% Mn, 1-5.5% Ni, 0.3-1% Cu and further, inevitably, ≤0.03% P, ≤0.01% S and ≤0.05% Cr.;COPYRIGHT: (C)2000,JPO
