Abstract

PURPOSE: To enhance the corrosion resistance of the resulting titled stainless steel and to prevent a cost rise and a cost change by reducing the amount of Mo added and adding W and Si in place of the Mo.
CONSTITUTION: This ferrite stainless steel with high corrosion resistance has a composition consisting of, by wt., ≤0.07% C, 0.4W2.0% Si, ≤1.0% Mn, 16.0W20.0% Cr, 0.3W0.7% Mo, 0.7W1.2% W and the balance Fe with inevitable impurities. This steel is almost equal to a conventional ferrite stainless steel contg. about 1% Mo in corrosion resistance, yet it is obtd. at a lower manufacturing cost and a stable price since expensive Mo with a large cost change is used by a smaller amount.
