PURPOSE:To provide a flux for welding by which build-up layers of high toughness and high strength are easily obtained by slag making agents contg. specific amts. of CaO, CaF2, etc., by deoxygenizing agents for alloying agents contg. specific amts. of C, Si, Mn, etc.. CONSTITUTION:The flux contg. 5-25% CaO or CaCO3, 3-30% CaF2, 2-30% Al2O3, 3-30% MgO, 5-25% SiO2 as slag making agents, contg. <=0.5% C., 0.2- 3.0% Si, 1.9-11.5% Mn, 0.4-4.5% Ni, 1.3-10.2% Cr, <=40% iron as deoxygenizing agents for alloying and consisting of the balance unavoidable impurities is prepd. If necessary, it is possible to contain >=1 kind of <=3.6% Mo, <=5.7% V as alloying agents and further 1 or 2 kinds of <=15% TiO2 or ZrO2 as other components of the slag making agents. |
