Hot Rolled Coil

Abstract: The present invention provides a hot rolled coil characterized by having prescribed chemical composition and by having a metal structure in which at a center part in the length direction when a crystal grain is defined as a region surrounded by a grain boundary having an orientation difference of not less than 15?? the average particle size of crystal grains is 5.0 8.0 ??m the average particle size of deposited material is 3.0 9.5 nm the difference between the maximum value and minimum value of particle size of the deposited material in the width direction is not more than 15.0% of the average particle size of the deposited material and at a center part in the width direction the difference between the maximum value and the minimum value of the particle size of the deposited material in the length direction is not more than 15.0% of the average particle size of the deposited material in the length direction.
