Abstract

The purpose of this study is to evaluate characteristics of plate forming by flame heating for E and EH36 TMCP steel. The characteristics of interest were heat-formability of TMCP steel and mechanical properties of heated area. For a given dimension, heat-formability of TMCP steel was inferior to that of a conventional steel because TMCP steel required more heating passes and time. Angular distortion and transverse shrinkage of TMCP steel decreased with an increase in line heating speed for given heating conditions. The mechanical properties of TMCP steel after plate forming by flame heating were high enough to satisfy the requirements.
