Abstract
The purpose of the present invention is to provide a steel member with excellent fatigue resistance characteristics in the plastic strain range, a hot-rolled steel sheet as the material therefor and production methods therefor. A steel member, which contains 0.031-0.200 mass% Ti and in the structure of which at least 0.005 mass% of the Ti is precipitated as precipitates with a particle size of 20 nm or less. A hot-rolled steel sheet for said steel member that contains 0.031-0.200 mass% Ti and in the structure of which at least 0.005 mass% of the Ti is present as Ti solid solution. A production method for said steel member in which, after molding of the hot-rolled steel sheet, heat treatment is performed wherein the member is heated to a temperature greater than 550°C and not exceeding 1050°C and then cooled at an average cooling rate of at least 10°C/s for the temperature range of 550-400°C. A production method for said hot-rolled steel sheet in which a steel slab containing 0.031-0200 mass% Ti is extracted under temperature conditions higher than the equilibrium solid solution temperature TTi determined from a specified formula, after which finish-rolling is completed at a temperature of at least TTi-400°C, the sheet is cooled at an average cooling rate of at least 10°C/s for the temperature range from TTi-400°C to TTi-500°C, and is coiled at a temperature of TTi-500°C or less.
