Abstract
The effect of molybdenum on notch toughness of austenitic stainless steel weld metal was investigated. The weld metals where molybdenum content varied from 0.1 to 2.9% and δ ferrite content 0 to 10.8%, were prepared by submerged arc welding. The absorbed energy of fully austenitic weld metal was constant independent of molybdenum content. However, in the case of eutectic δ ferrite weld metal, the absorbed energy decreased monotonously with molybdenum content. In the weld metal of primary δ ferrite, the absorbed energy was constant up to 2.3% Mo and began to drop in the specimen above 2.9% Mo where the concentration of molybdenum within the δ ferrite grain was more than 5%. Multiple regression analysis revealed that C, Cr and Mo had a reducing action on toughness.
