• Solidification cracking susceptibility of a high manganese Fe-Cr alloy which is one of the candidate materials for the first wall of fusion reactor was investigated by hot cracking tensile test. The effects of C, Si, S, P, N and Mn on the cracking susceptibility are such that hot cracking susceptibility increases remarkably with increases of C, S and Si. A fully austenitic weld metal with high nitrogen content was found to be free of crack. Even though carbon and nitrogen are an austenite former, carbon containing welds show a high crack tendency whereas nitrogen containing ones are free of cracks. Welds with higher Mn content show the least crack susceptibility. The high manganese Fe-Cr alloys show less hot cracking susceptibility than SUS 316 stainless steel.
