Results are presented from a theoretical and experimental investigation on the behaviour of the AISI 316 H steel, which is an austenitic stainless steel important for applications in nuclear installations. The results of various tensile tests performed at different strain rates (0.001-1000 l/s) and temperatures (20-650 C) are reported, and the material constants of the dislocation-mechanics based Armstrong-Zerilli constitutive model have been calculated. Using the obtained material model, two-dimensional simulations have been carried out of cylinder impact tests (Taylor tests) at various impact velocities. The numerical predictions have been directly compared with the results of No. 10 reverse impact tests performed with a light gas gun.
