A heat-resistant austenitic stainless steel is disclosed. This steel essentially consists of: not more than 0.06% C, 1 - 4% Si, 0.5 - 4% Mn, not more than 0.035% P, not more than 0.005% S, 10 - 17% Ni, 14 - 20% Cr, 1 - 4% Mo, 0.01 - 0.5% A8, not more than 0.035% N, and balance essentially Fe, and may further contain small amounts of any of Cu, REM and B and the composition thereof is adjusted so that a limited amout of .delta. -ferrite appears in solidification. The steel has excellent hot salt corrosion resistance, weldability, salt errosion resistance of the weld and hot-workability.
