It is shown that the T_(GC) may be obviously raised byadding even a little Ti to the base steels so as to precipitate a great deal of fineTi-bearing grains of about 10 nm. The T_(GC) does not increase with the cooling rate,as it is over a certain critical value. The T_(GC) is insensitive to any variation ofN content at simulated cooling condition of 150mm continuouscast slab. TheT_(GC) may be dropped down about 100℃ by adding 0.33 wt-% Mo to the steels.The sensitivity of T_(GC) to cooling condition is related with Ti and N contents.
