摘　　要：采用不同弯心直径,测定了屈服强度为590 MPa级10CrNi3MoV钢焊接接头弯曲试验后不同部位的伸长率,并结合该级别钢弯曲试验的其它相关规定,说明了现行的10CrNi3MoV钢焊接接头弯曲试验中弯心直径的规定比较苛刻,亟待修订。Abstract：With different bend diameters in bend test of 10CrNi3MoV steel welded joints, the percentage elongations of different parts have been determined. In contrast with other relating prescripts in bend test of the same grade steel, the given stipulation for bend diameter in bend test of 10CrNi3MoV steel welded joints proves to be rigid and need to be revised.
