PURPOSE: To restrict formation of coarse grain and to improve cold forgeability of ferritic electric stainless steel by compositely adding specified quantity of Ti, B Mo and Cu to the above steel.

CONSTITUTION: This steel consists of ≤0.02wt.% C, 0.01-0.05% Si, 0.01-0.50% Mn, 7.00-20.00% Cr, 0.30-2.00% Mo, 0.01-2.00% Cu, 0.05-0.50% Ti, 0.05-3.00% Al, 0.0005-0.05% B, ≤0.05% Ni and residue substantially consisting of Fe. Moreover, if necessary, at least a kind of ≤1.00% Nb, 1.00% V, moreover at least one kind of ≤0.30% Pb, ≤0.03% Ca, ≤0.20% Se and ≤0.20% S is allowed to contain. As crystal grains become fine and have uniform structure in this component, high cold forgeability electric stainless steel having all of excellent cold forge-ability, favorable magnetic characteristics and corrosion resistance can be obtained.
