Definitions
- Ta forms alloy carbides or alloy carbonitrides, and contributes to increasing the strength of steel. It is also believed that Ta has the effect of significantly suppressing coarsening of precipitates when partially dissolved in Nb carbides or Nb carbonitrides to form complex precipitates, such as (Nb, Ta) (C, N), and the suppression of coarsening of precipitates serves a stable contribution to increasing the strength of the steel sheet. Therefore, Ta is preferably added to steel.
- the above-described precipitate stabilizing effect is obtained when the Ta content is 0.0010 mass % or more. However, excessively adding Ta does not increase this effect, but instead the alloying cost ends up increasing. Therefore, when Ta is added to steel, the content thereof is in a range of 0.0010 mass % to 0.1000 mass %.
- the high-strength galvanized steel sheet disclosed herein may be produced by performing well-known and widely-used galvanizing treatment on the above-mentioned high tensile strength steel sheet.
