Taseto GFW410Cb description: TASETO GFW410Cb is used for overlay welding of 13%Cr steel. As its all weld metal contains Nb, GFW410Cb provides fully ferritic weld metal with high ductility and free of quench hardenability. Delayed craking is prevented with lower preheat and interpass temperature compared with martensitic steel weld metal such as Type 410 stainless steel.
