![]() Reheat cracking may occur in low alloy steels containing alloying additions of chromium and molybdenum or chromium, molybdenum and vanadium when the welded component is being subjected to post weld heat treatment, such as stress relief heat treatment, or has been subjected to high temperature service (typically in the range 350 to 550☌).Ĭracking is almost exclusively found in the coarse grained regions of the heat affected zone (HAZ) beneath the weld, or cladding, and in the coarse grained regions within the weld metal. General guidelines on best practice are given so that welders can minimise the risk of reheat cracking in welded fabrications. The characteristic features and principal causes of reheat cracking are described. National Structural Integrity Research Centre.Structural Integrity Research Foundation. ![]()
