Optimization of welded stainless steel and nickel alloy structures for elevated temperature service
- Tillack Consulting Associates, Inc., Huntington, WV (United States)
The fabrication of materials such as the austenitic stainless steels and the nickel-base alloys, all of which share a face-centered-cubic structure, presents problems that the ferritic materials do not have. A large difference is the tendency for the austenitic materials to suffer from hot cracking, or solidification cracking, during welding. This characteristic can be dealt with d proper welding procedures are used, such as control of weld heat input and travel speed to obtain a properly contoured weld pool. Residual stresses, caused by fabrication and welding, can be a problem in certain service conditions, such as intermediate temperature exposure where there is little stress relief and the residual stresses are higher than the rupture strength of the material. In this case, it is important to give a stress relief heat treatment prior to putting the component into service.
