    • A welding wire for use in submerged arc welding of Cr-Mo steels comprising less than 0.25% C, less than 0.60% Si, 0.15-1.50% Mn, 0.50-10.0% Cr and 0.40-2.50% Mo on the basis of the weight ratio comprises 0.05-0.19% C, less than 0.60% Si, less than 1.6% Mn, 0.50-10.5% Cr and 0.30-2.50% Mo as the basic elements boron and nitrogen added thereto as the essential elements each in the range of 0.0001-0.25% B and 0.010-0.040% N; and at least one of titanium, zirconium and aluminum further incorporated therein each in the range of 0.01-0.30% Ti, 0.05-0.30% Zr and less than 0.40% Al, while being adjusting such that the sum of the elements: Ti+Al+Zr+10B lies within a range between 0.003-0.40% on the basis of the weight ratio. The welding wire of the novel composition can provide weld alloy steels with high strength and excellent toughness even at low temperature.
    • 一种用于Cr-Mo钢的埋弧焊的焊丝,其包含基于重量的小于0.25%C,小于0.60%Si,0.15-1.50%Mn,0.50-10.0%Cr和0.40-2.50%Mo 的比例包括0.05-0.19%C,小于0.60%Si,小于1.6%Mn,0.50-10.5%Cr和0.30-2.50%Mo作为基本元素添加硼和氮作为必需元素,各自在0.0001 -0.25%B和0.010-0.040%N; 进一步掺入钛,锆和铝中的至少一种,其中分别在0.01-0.30%的Ti,0.05-0.30%的Zr和小于0.40%的Al的范围内,同时进行调节,使得元素的总和:Ti + Al + Zr + 10B基于重量比在0.003-0.40%的范围内。 新型组合物的焊丝即使在低温下也能提供高强度和优异韧性的焊接合金钢。
