ABSTRACT:
A powder metallurgy wire for a dot printer is disclosed which consists, by weight, of 1.5 to 2.8% C, 7.5 to 12.0% Cr, at least one kind selected from the group consisting of not more than 18.0% W and not more than 11.0% Mo which W and Mo meet the relationship of 12.ltoreq.W+2Mo.ltoreq.22, 3 to 10% V, 1.0 to 10% Co, not more than 1.0% Si, not more than 1.0% Mn, the balance Fe and incidental impurities, the value of the difference of (C-Ceq) being in the range of -0.5 to -0.15 where Ceq=0.06.times.%Cr+0.033.times.%W+0.063.times.%Mo+0.2.times.%V. According to the composition, corrosion resistance and wear resistance are considerably improved, with light weight and high toughness.
