MEACTOS environmentally-assisted crack initiation data for constant extension rate tensile tests in BWR/NWC and PWR environments on Alloy 182 Ni-based alloy and cold-worked 316L stainless steel

Data collection created at PSI, SCK CEN, CIEMAT, VTT, ZAG, Framatome GmbH, University of Manchester, RATEN ICN, and EC JRC in the scope of the H2020 MEACTOS project investigating the mitigation of environmentally-assisted cracking through optimisation of surface condition. The work was concerned with SSRT/CERT accelerated tests on flat tapered tensile specimens in BWR/NWC and PWR environments to determine the stress corrosion cracking threshold stress. The materials investigated were Ni-based weld metal Alloy 182 and cold-worked 316L stainless steel.
