- 論文の詳細を見る
The effects of Mn and N on the cracking susceptibility of SUS (AISI) 310S fully austenitic stainless steel weld metals were investigated by making the Trans-Varestraint test and other hot cracking tests. The beneficial effect of Mn in reducing cracking was confirmed, and it was revealed that its degree was greater as the S content was larger. For commercial SUS310S (0.02-0.03%P, 0.003-0.02%S) the optimum Mn content was about 3 to 6% according to the S content. The metallurgically beneficial effect of Mn was attributed to the reduction in the deleterious effect of S. It was also found that N had a neutral effect or a slightly detrimental effect on the cracking resistance of commercial SUS310S weld metals.
