Abstract

Recently, many kinds of weathering steel were widely used in steel bridges. 1%Ni-advanced weathering steel is one of new types of weathering steel. It was considered that the quality of this steel has been remarkably improved. However, when it comes to how much, it has not been clarified. In this paper, we investigated the 753 of 1%Ni-advanced weathering steel on the basis of the mill sheet in order to clarify their quality. Investigated items were tensile strength, yield strength, charpy-absorbed-energy, elongation and yield ratio, and these steel mechanical properties were shown. We also showed the degree of improvement in the quality, comparing with the conventional weathering steel data.
