..., and 1144. As a rule, steels with carbon contents and hardenability greater than 1037 are difficult to water quench ( Ref 22 ). Some steel grades with high manganese are prone to microsegregation of manganese, gross segregation of chromium, and thus are prone to cracking. These include 1340, 1345, 1536...

... of unresolvable pearlite aligned in bands along the longitudinal direction of the pipe. The pearlite grains occur in lean alloy microsegregation bands where local hardenability is low. The structure, shown in Fig. 5 , is typical of a low alloy hardenable steel in the normalised condition, Fig. 5 Upper...

... analysis, it was found that microsegregation of titanium, sulphur and manganese occurred in the dendrite interstices of the crack surface. The microsegregation of titanium and manganese in combination with sulfur can be expected to broaden the temperature range of resolidification of the fused metal...

Chemical composition of the alloy was determined by transmission spectroscopy on an appropriate specimen sectioned from the tube. Microstructural analysis and determination of the crack propagation mode were performed by light optical...
