    • A flux cored wire for duplex stainless steel and a manufacturing method thereof are provided. The flux cored wire can include a sheath and a flux filled into the sheath. The flux cored wire comprises about 24.0-30.0 wt % Cr, about 7.0-10.5 wt % Ni, about 2.0-4.0 wt % Mo, about 0.10-2.50 wt % Cu, about 0.40-1.00 wt % Si, about 1.5-3.0 wt % Mn, about 0.10-0.30 wt % N compound (converted value of N), and the remainder including Fe and inevitable impurities on the basis of the total weight of the wire. The flux comprises about 6.50-12.00 wt % of TiO2+SiO2+ZrO2+Al2O3, about 0.10-0.50 wt % of Li2O+K2O+Na2O, about 0.10-2.00 wt % of the other oxides, and about 0.10-0.50 wt % of metal fluoride (converted value of F) on the basis of the total weight of the wire. The flux can be filled into the sheath at a ratio of about 26-35%.
    • 提供了一种用于双相不锈钢的药芯焊丝及其制造方法。 药芯焊丝可以包括护套和填充到护套中的焊剂。 药芯焊丝包含约24.0-30.0重量%的Cr,约7.0-10.5重量%的Ni,约2.0-4.0重量%的Mo,约0.10-2.50重量%的Cu,约0.40-1.00重量%的Si,约1.5-3.0重量% %Mn,约0.10-0.30重量%的N化合物(转化值N),其余包括基于导线总重量的Fe和不可避免的杂质。 焊剂包含约6.50-12.00重量%的TiO 2 + SiO 2 + ZrO 2 + Al 2 O 3,约0.10-0.50重量%的Li 2 O + K 2 O + Na 2 O,约0.10-2.00重量%的其它氧化物和约0.10-0.50重量% 金属氟化物(F的转化值)基于导线的总重量。 焊剂可以以约26-35%的比例填充到护套中。
