| description | PROBLEM TO BE SOLVED: To provide an austenitic stainless steel good in heat fatigue characteristics.SOLUTION: There is provided an austenitic stainless steel having a chemical component containing 16 mass% to 25 mass% of Cr, 10 mass% to 15 mass% of Ni, 1.1 mass% to 5.0 mass% of Si, 0.08 mass% to 2.0 mass% of Mn, 0.04 mass% or less of P, 0.01 mass% or less of S, 0.05 mass% to 0.3 mass% of Nb and 0.02 mass% to 0.25 mass% of N and the balance Fe with inevitable impurities. In a range of such the chemical component, alloy component is adjusted so that thermal expansion coefficient from a room temperature to 1,000°C becomes 19.5×10/K or less. Also the alloy component is adjusted so that Young's modulus at 500°C becomes 155 GPa or less. Then thermal fatigue characteristics can be enhanced by thus regulating thermal expansion coefficient and high temperature Young's modulus.SELECTED DRAWING: None
