焊接材料及焊接接头
摘要：
(i)一种奥氏体系不锈钢用焊接材料，其为含有Nb和/或V的耐晶界腐蚀性优异的SUS310系不锈钢母材的焊接中使用的焊接材料，化学组成为：按质量%计，含有C：0.02%以下、Si：2%以下、Mn：2%以下、Cr：26～50%、N：0.15%以下、P：0.02%以下、S：0.002%以下以及满足[5≤Ni≤Cr-14]的量的Ni，剩余部分由Fe和杂质组成。(ii)由上述母材和使用焊接材料而成的焊接金属形成的奥氏体系不锈钢的焊接接头。
摘要（英）：

(i) A welding material for austenitic stainless steel, which is used for welding of an SUS310 stainless steel matrix that contains Nb and/or V and has excellent intergranular corrosion resistance, and which contains, in mass%, 0.02% or less of C, 2% or less of Si, 2% or less of Mn, 26-50% of Cr, 0.15% or less of N, 0.02% or less of P, 0.002% or less of S and Ni in an amount satisfying [5 = Ni = Cr - 14], with the balance made up of Fe and impurities. (ii) A welded joint of austenitic stainless steel, which is composed of the above-described matrix and a welded metal that is obtained using the welding material.
