Abstract
PURPOSE: To improve strength and to maintain high-heat strength at 450W450°C even after a long-period heat treatment and creep rupture strength by adding a specific ratio of V to a welding material for a Cr-Mo high-temp. steel.
CONSTITUTION: The core wire has the chemical components of the compsn. contg., by wt%, 0.05W0.16% C, ≤0.25% Si, 0.50W1.10% Mn, 2.00W3.50% Cr, 0.80W1.50% Mo, and 0.40W0.60% V, and consisting of the balance Fe and inevitable impurities. A coating material contg., by wt%, 30W70% metallic carbonate such as CaCO3, 5W30% metallic fluoride such as CaF2, and 0.5W5% Mg, and contg. others such as deoxidizing agent, arc stabilizer and binder is coated around such core wire. The V is added to the welding material within the range where the decrease of C by the excessive formation of the carbide in a weld metal is obviated in the above-mentioned manner, by which the higher strength is obtd. Fine V4C3 is deposited in the weld metal by the addition of the V, by which the high-temp. strength at 450W500°C even after the long-period heat treatment and the creep rupture strength are maintained.
