Problem to be solved: to provide a stainless steel which has excellent strength and corrosion resistance and is easy to be machined and processed in the case where it is used in the application of strength and corrosion resistance.Mass%C: 0.001 to 0.100%Si: 0.01 to 5.00%Mn: 0.01 to 2.00%P: 0.050% or lessS: 0.0100% or lessCr: 9.0 to 30.0%Ni: 0.01 to 0.50%Ti: 0.01 to 1.00%Al: 0.010 to 5.00%N: 0.001B: 0.0001 to 0.0050%The remainder is Fe and impurity.And the amount of SiTi and Al content (mass%)Contains chemical components that satisfy 2Al + si-10ti ≧ 0.The stainless steel is characterized in that the particle size number of the cross-sectional structure in the rolling direction is 6.0 to 9.0 or less.No selection
