SOLUTION: The high strength steel has an effective combination of a trap site having a weak hydrogen capture action and a trap site having a strong hydrogen capture action. The amount of hydrogen discharge in a low temperature region H1 and H3 and the amount of hydrogen discharge in a high temperature region H2 and H4 obtained by temperature raising inspection directly after the charge of hydrogen and after leaving at 80°C for 24 hr, respectively, are measured. In this high strength steel, H1 is adjusted to 1.0 to 10 mass ppm and H2 to 0.3 to 5 mass ppm, and conditions H3/H1≥0.05 and H4/H2≥0.8 are satisfied. Further, the dimension and number of precipitates to form the trap site having the weak hydrogen capture action and the trap site having the strong hydrogen capture action and the average Ti content included in these precipitates are regulated to a prescribed value, respectively.

摘要： PROBLEM TO BE SOLVED: To provide steel with colored zinc-plated film by which a galvanized layer is hard to be worn, and. even if wear is caused, a silver - white metallic face is not easily exposed, and to provide a production method for producing the steel having the film with high operability. SOLUTION: The steel has a colored zinc-plated film, and is obtained by incorporating carbon into the galvanizing film. By the incorporation of the carbon into the zinc-plated film, the film is colored into a black base, and, by the lubrication action of the carbon, its wear resistance can be expected. Further, even when the galvanizing layer is worn, the black base is retained owing to the direct presence of the carbon in the zinc-plated film, an the silver - white zinc-plating is not easily exposed. Additionally, its corrosion resistance is attained by the zinc-plating.
