AUSTENITE SYSTEM STAINLESS STEEL FILLER ROD WITH EXCELLENT HIGH TEMPERATURE CHARACTERISTIC

摘要

PROBLEM TO BE SOLVED: To obtain a filler rod with excellent high temperature characteristic by coating a coating agent around a core wire containing carbonate, silica, and SiO2 around a core wire at specific weight proportion against the overall weight of a coating agent, and composing the rod of Mo, W, Cu, Nb, V, N, and the balance of Fe and inevitable impurities at the core wire weight ratio of total of one or both of the core wire and the coating agent. ;SOLUTION: A coating agent containing 20-45% carbonate, 10-30% silica, and 3-18% SiO2 at weight % against the overall weight of the coating agent is coated on this filler rod. Furthermore, the rod is composed of 0.2-5% Mo, 1-5% W, 0.1-2.5% Cu, 0.1-2.0% Nb, 0.1-2% V 0.05-0.3% N, and the balance of Fe and inevitable impurities, at the core wire weight ratio of total of one or both of the core wire and the coating agent. It is preferable that 0.016-0.05% P is contained, Nb/V is 0.1-0.5, and Mo is 0.2-1.1% at the core wire weight ratio of total of one or both of the core wire and the coating agent.;COPYRIGHT: (C)2000,JPO
