| titleOfInvention | Steel material having microstructure and method for producing the same |
| abstract | PROBLEM TO BE SOLVED: To form fine crystal grains while reducing the amount of alloy addition that increases manufacturing cost, and in addition to increasing strength, automobiles, containers, tanks, buildings, shipbuilding, civil engineering, rails, etc. in which steel materials are generally used High-strength steel material that is compatible with high ductility, high toughness, brittle cracking resistance, wear resistance, high fatigue, and good surface treatment properties required for various applications such as electrical equipment and steel pipes. Manufacturing. SOLUTION It is not essential to contain Cr and Ni, N is contained in an amount of 0.05 to 4.0%, Mn Is controlled to 10.0% or less, Si and Al to 4.0% or less, heat treatment is performed at a temperature at which the austenite phase abundance ratio is 70% or more, and then cooled, the ferrite phase crystal grains in the metal structure The diameter is set to 3.0 μm or less. In order to make the effect of refining the structure more prominent, in addition to the heat history such as the heating temperature / time and the heating / cooling rate, the number of heat treatments, the application of strain during the heat treatment, and the like are performed. [Selection figure] None |
