<P>PROBLEM TO BE SOLVED: To provide a highly corrosion-resistant austenitic stainless steel having excellent tensile properties and used for piping for a heat exchanger. Ž<P>SOLUTION: The highly corrosion-resistant stainless steel having excellent tensile properties is obtained by subjecting a steel comprising, by mass, 0.025 to 0.060% C, ≤1.0% Si, ≤2.0% Mn, ≤0.035% P, ≤0.010% S, 11.0 to 13.5% Ni, 16.5 to 18.0% Cr, 2.0 to 3.0% Mo, ≤0.04% Al, 5×C to 0.50% Ti, 0.05 to 0.08% V and 0.010 to 0.025% N, and the balance Fe with inevitable impurities to hot extrusion.
