Foil specimens in a thickness range of 20 - 500 μm are increas ingly used in simulation experiments where neutroninducedchanges of mechanical properties are simulated by light ion bombardment. For a reliable transfer of such data to bulk material, the mechanical behavior of foil specimens in comparison with bulk specimens must be known. In this work results of tensile tests on cold worked and solution annealed type 316 stainless steel foils of 200 μm thickness are reported for temperatures between 20 and 900° C. The investigated material was part of a heat supplied by JRC Ispra. lt shall serve as reference material for irradiation experimentswithin the Euratom Fusion Programme
