THERMOPHYSICAL PROPERTIES OF STAINLESS-STEELS

Experimental data available for the thermophysical properties of stain less steels have been searched, compiled, critically evaluated, analyz ed, and correlated. Particular attention was given to material charact eristics such as alloy composition, microstructure, and conditioning t reatments. Thermal conductivity and electrical resistivity at low temp eratures, and in some cases above room temperature, are comparatively more sensitive to these material differences. Properties for which dat a evaluation has been done include thermal conductivity, heat capacity , thermal linear expansion, thermal diffusivity, thermoradiative prope rties, electrical resistivity, and magnetic susceptibility, and, in a few cases, thermoelectric power, viscosity, and optical constants. Gen erally, sufficient data are available for the generation of evaluated data (recommended values) for elevated temperatures, and in many cases for low temperatures also. Stainless steels covered include the more common austenitic, ferritic, martensitic, and precipitation-hardened t ypes. In all, more than 40 stainless steels are included in this effor t.
