In the present investigation J-R curves have been determined for SS 316 LN with nitrogen contents of 0.08, 0.14 and 0.22 wt% at 298, 653 and 823 K. Elastic-plastic fracture toughness (J(0.2)) corresponding to 0.2 mm crack extension, was determined from the J-R curves. For all test temperatures, J(0.2) values were the highest for the steel with 0.14 wt% nitrogen. (C) 2014 The Authors. Published by Elsevier Ltd.
