ABSTRACT:
A decarburization-annealed steel strip as an intermediate material for grain-oriented electrical steel strip having good secondary recrystallization and excellent electrical properties is provided by causing a steel strip to possess a micro-structure in which the primary recrystallization grains have an average diameter d of not less than 15 .mu.m and a coefficient of diameter deviation .sigma.* of not more than 0.6.
