The present invention relates to a martensitic stainless steel that can be
used in manufacturing articles such as a shaft or an impeller which
require high mechanical strength and corrosion resistance and provides a
martensitic stainless steel comprising less than 0.06 wt. % C, less than
2.5 wt. % Si, less than 2.5 wt. % Mn, 1.0-6.0 wt. % Ni, 10.0-19.0 wt. %
Cr, 0.5-6.0 wt. % W, less than 3.5 wt. % Mo, less than 0.5 wt. % Nb, less
than 0.5 wt. % V, less than 3.0 wt. % Cu, 0.05-0.25 wt. % N, and the
remainder being Fe and minor impurities.
