Abstract
Combined cycles for stress relieving of different equipment are inevitable in a pressure vessel industry, since the furnaces are generally too big to accommodate only a few similar vessels and stress relieving is too often required beyond the mandatory requirements of the code. Before proposing a combined cycle one must have a thorough knowledge about the materials, which go for the heat treatment. It is better, if the materials and welding are subjected to simulated heat treatment and tested to assess the influence of proposed heat treatment. Two such experiments, which have been conducted here to evolve the deterioration in mechanical properties on prolonged stress relieving are given in this paper and the data is analysed.
