Grade 321 Stainless Steel Technical Data - ASKzn PDF Thermal characterization of austenite stainless steel (304) and CNT ... This article discusses the properties and applications of stainless steel grade 304 (UNS S30400). The emissivity, ε, of the surface of a material is its effectiveness in emitting energy as thermal radiation and varies between 0.0 and 1.0.. By definition, a blackbody in thermal equilibrium has an emissivity of ε = 1.0.Real objects do not radiate as much heat as a perfect black body. material plays an important role in the overall thermal performance of the system because it establishes the system emissivity. At 80 K, the emissivity of the undamaged silver coating was found to be 0.0035 with a standard uncertainty of 0.00033 (cover-age factor k = 1), less than one-tenth of the emissivity of the bare stainless steel plate.
