摘要： PURPOSE:To improve the strength, toughness and weldability of a coated electrode for Cr-Mo steel by coating a coating material which contains specified weight ratios of metallic carbonates, metallic fluorides and metallic oxides and is limited of component compsn. at specific weight ratios on an electrode which is limited of component compsn. CONSTITUTION:A coating material contg., by weight, 30-60% metallic carbonates, 10-30% metallic fluorides and 4-20% metallic oxides is coated on the outside circumference of a core wire in such a way that the ratio of the coating material to the total weight of the electrode attains 23-33%, and 0.06-0.12% C, 1.0-1.8% silicon, 0.4-1.0% Mn, 6.5-8.7% Cr, and 1.5-2.0% Mo based on the total weight of the electrode are contained in the covering material and/or the core wire. The reasons for limiting the component compsns. in the covering material and core materials lie in that if the carbon is too much weldability degrades. If the silicon is too little, blowhole are produced in deposited metal and if the silicon is too much, toughness degrades. If the Mn is too much, as- welded hardness is too high. If the Mo is too little, high temp. hardness is not obtained and if the same is too much, the deposition of a ferrite phase increases.

摘要： PURPOSE:To form weld zones having high toughness and low sensitivity to temper-brittleness to a titled alloy steel by contg. respective components of C, Mn, Si, Cr, Mo, Al, N, Ni in a core wire and a coating material so as to satisfy specific conditions. CONSTITUTION:This coated electrode for Cr-Mo low alloy steels is produced by contg. such alloy components that satisfy the respective conditions expressed by the equations (Bw; the coefft. of yield of the elements contained in a core wire in deposited metal, Bf; the coefft. of yield of the elements contained in a coating material in deposited metal, (element symbol %) W; wt% of the elements contained in the core wire based on the total weight of the core wire, (element symbol %) f; wt% of the elements contained in the coating material based on the total weight of the coating material, Af; the weight ratio of the coating material to be coated based on the total weight of the electrode) in one or both of the core wire or the coating material. As a result, AlN is formed sufficiently in deposited metal, and the weld zones having high low temp. toughness and low sensitivity to temper-brittleness are formed.
