圧延Ｈ形鋼の溶接性を含む機械的性質

－電炉材と高炉材の性能比較－

抄録

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.
