WELDING MATERIAL FOR HEAT RESISTANT STEEL |
摘要 |
A welding material for heat resistant steel comprises: flux and a sheath surrounding the flux. The welding material comprises, by wt %, carbon (C): 0.03% to 0.3%, manganese (Mn): 0.5% to 3.0%, silicon (Si): 0.1% to 2.0%, phosphorus (P): 0.01% or less, sulfur (S): 0.01% or less, nickel (Ni): 20% to 40%, chromium (Cr): 15% to 35%, TiO2: 3% to 7%, SiO2: 0.5% to 2.5%, ZrO2: 0.5% to 2.5%, and a balance of Fe and inevitable impurities. The sheath comprises an Ni—Fe-based alloy having a nickel content of 30% to 50%. |
