• 論文の詳細を見る

• High-nitrogen austenitic stainless steel weld metals were obtained by using regular type 316 electrode wire and N_2, Ar, N_2-Ar, N_2-CO_2 mixture shielding gas. Low temperature tension and impact test on deposited metal specimens were carried out. High-nitrogen austenitic stainless steel weld metals give a tensile strength of about 65 and about 130kg/mm^2 at 0℃ and -196℃ respectively. At impact test, high-nitrogen austenitic stainless steel weld metals made in pure N_2 shielding gas give an absorbed energy of about 17 and about 6kg-m at 0℃ and -196℃ respectively. Weld metals made in N_2-CO_2 mixture shielding gas give a smaller absorbed energy than in N_2-Ar mixture shielding gas. Oxygen free high-nitrogen austenitic stainless steel weld metals made in N_2, and N_2-Ar mixture shielding gas show a good mechanical property in the test temperature range from 0℃ to -196℃.
