Surface Tension and Thermal Conductivity of NIST SRM 1155a (AISI 316L Stainless Steel)

Abstract NIST SRM 1155a is an AISI 316L stainless steel (Cr18–Ni12–Mo2) and Standard Reference Material (SRM) intended for use with test methods elemental analysis. In a previous paper “Measurement of thermophysical properties solid liquid steel”, we already published reliable high temperature the phase this material such as dependent enthalpy, density electrical resistivity, well specific heat capacity phase. paper, add additional obtained by ohmic pulse-heating laser flash method, namely thermal conductivity diffusivity function temperature. Furthermore report surface tension measurement results means electromagnetic levitation. Simulation processes like additive manufacturing, welding, cutting or metal casting depend on above named quantities input data. Ohmic levitation are so called “containerless” investigation techniques no significant chemical reactions hot alloy its surrounding occur. The data presented here compared to available literature accompanied uncertainty analysis according “Guide Expression Uncertainty in Measurement”.
