Abstract: The fracture behavior for welded joint of new genergtion fine grained steel SS400 was investigated and assessed on the basis of fitness for purpose philosophy.The actual critical defect sizes for the SS400 base metal and its weld HAZ(heat affected zone) defined by the gross yielding criterium have been determined

Key words: fine grained steel, general yiellding, wide plate test,
