Abstract

PURPOSE:To obtain an unidirectional silicon steel plate having a high magnetic flux density by forming a plate of silicon steel containing specific quantities of Si, Mn and Al, decarburizing and annealing said plate and soaking the resulting plate in an atmosphere consisting of H2-N2 in a specific quantity and under specific conditions to thereby denitrify the plate.
