Effects of pre-annealing and hydrogen flow rate on final texture and magnetic induction have been investigated in inhibitor-free 100 μm thick 3% Si–Fe strips containing 18 ppm sulfur. Without any pre-annealing, the strip showed a low magnetic induction, due to various {1 1 0}, {1 0 0} and {1 1 1} final texture components. The number and the area fraction of {1 1 0} grains increased with increasing pre-annealing temperature and hydrogen flow rate. A pre-annealing temperature range that results in the sharp {1 1 0} 〈0 0 1〉 texture is observed, depending on the hydrogen flow rate.
