Abstract
The influence of post weld heat treatment on hardness and impact tough ness properties of weldments of 1Cr0.5Mo and 2.25Cr1Mo steels has been investigated. Post weld heat treatment significantly reduced the hard ness and the impact transition temperature and increased the upper she lf energy. The decrease in hardness was essentially larger for 2.25Cr1 Mo than for the other steel, probably due to the presence of martensit e in the as-welded condition in the former material. The decrease in t he impact transition temperature was largest for 1Cr0.5Mo.
