The thermal conductivity of AISI 304L stainless steel
- Oak Ridge National Lab., TN (United States)
A compilation and critical analysis of the thermal conductivity ({lambda}) of AISI 304 stainless steel (SS) between 100 and 1,707 K has been given in the literature. The author represented his recommended values of {lambda} by an inflection in the {lambda} versus temperature relationship between 300 and 500 K. Because a physical mechanism had not been identified that would produce such a temperature dependence in {lambda} of 304 SS, interest was generated in the possible existence of an as yet undiscovered phenomenon that might cause such an inflection. Consequently, experimental verification of the inflection was sought. The present paper presents recent measurements of {lambda}, the electrical resistivity, and the absolute Seebeck coefficient of 304L SS from 300 to 1,000 K and of the thermal diffusivity ({alpha}) from 297 to 423 K. The {lambda} values computed from the {alpha} measurements were within {plus minus} 1.6% of the directly measured {lambda}. An inflection was not observed in the temperature dependence of {lambda} between 300 and 500 K. After careful evaluation and because a physical mechanism still has not been identified which would produce such an inflection, the authors conclude that the inflection, the authors conclude that the inflection in the {lambda} vs T relationship reported in the literature was caused by the data analysis technique.
