Abstract
There is provided a method of manufacturing a titanium (Ti)-containing austenitic stainless steel sheet having a high degree of surface quality by using a twin roll strip caster. The method includes controlling a composition of molten steel such that a TiN precipitation temperature may be higher than a temperature of the molten steel in a tundish (T/D) by at least 50° C. (ΔT≧50° C.), the TiN precipitation temperature being defined by the following formula 2:
