Super-duplex stainless steel 2507 was found to have a hardness of 289 ± 5 which is higher than the weld zone, thereby making the hardness profile sharply higher in this region. Additionally, the grain coarsening in CGHAZ also contributes towards a sharp increase in hardness profile across the weld fusion boundary on the super-duplex side.
