Weldability of modified 9Cr-1Mo steel
The weldability of modified 9Cr-1Mo steel has been investigated by numerous organizations including Oak Ridge National Laboratory over a period of several years. The results of the various studies are summarized. Weldability evaluations have included hot cracking susceptibility, reheat cracking response, hydrogen-assisted cracking susceptibility, and the selection of consumables for three welding processes. Weldment mechanical properties have been determined for the gas tungsten arc, submerged arc, and shielded metal arc welding processes. Dissimilar metal weldments between modified 9Cr-1Mo steel and austenitic stainless steels have been produced with good results. Evaluation of the weldments and various tests has indicated that there are no major concerns regarding the weldability of modified 9Cr-1Mo steel.
