Relationship between Mechanical properties and Chemical compositions in steel for bridges (Part.l :Relationship between Tensile strength, Yield strength and Chemical compositions)

Abstract

In the past, we had investigated the number of 1412 steel on the basis of the mill sheet in order to clarify these steel quality, and mechanical properties and chemical compositions of these steel had been shown[1] [2] . However, in these papers, the relationship between their mechanical properties and chemical compositions had not been discussed. In this paper, we investigated the relationship between mechanical properties(tensile strength and yield strength) and chemical compositions(Carbon, Silicon and Manganese) including PCM and Ceq, and these results were shown.
