| 摘要 |
The present invention relates to a welding material for a heat resistant steel, capable of inhibiting the generation of a crack in a weld zone of a heat resistant steel. The welding material composed of 0.03-0.3 wt% of C, 0.5-3.0 wt% of Mn, 0.1-2.0 wt% of Si, no more than 0.01 wt% of P, no more than 0.01 wt% of S, 20-40 wt% of Ni, 15-35 wt% of Cr, 3-7 wt% of TiO2, 0.5-2.5 wt% of SiO2, 0.5-2.5 wt% of ZrO2, and the remainder includes Fe and inevitable impurities. An outer shell is an Ni-Fe based alloy containing Ni of 30-50%. |
