Mechanical properties including weldability of rolled H section steels

—Property comparison between electric arc furnace steels and blast furnace steels—

Abstract

Authors report experimental results on mechanical properties including weldability of rolled H section steels. The investigation is performed on arc- electric furnace steels and those of blast furnaces. The experiment was divided into the base-metal examination and the weld examination, and was carried out. The examination carried out chemical analysis, a tensile test, a hardness test, a Charpy impact test, nonmetallic inclusion examination, etc. And the reappearance thermal cycling test which feeds back the thermal hysteresis of actual welding was also carried out.
