Abstract

A heat-resistant ferritic stainless steel sheet having excellent oxidation resistance while being low in cost and optimal for use in exhaust system components, wherein mass % falls within the following ranges: C: 0.015% or less, N: 0.020% or less, P: 0.04% or less, S: 0.001% or less, Si: 0.3-1.5% or less, Mn: 0.3-0.7% or less, Cr: 11.0-17.0%, Cu: 0.8-1.5%, Ni: 0.05-1.0%, V: 0.5% or less, Al: over 0.01 up to 0.1%, Ti: 10(C+N) to 0.3%. Also, the element content of the elements in the ferritic stainless steel sheet having excellent oxidation and thermal resistance has been mutually adjusted in a manner such that the value of γ defined in formula (1) is 35 or less.
