Applied Sciences Free Full-Text Dissimilar Rotary Alloy 625 Overlays on Carbon Steel Cracking Metal and Additional strengthening of the Inconel 625 is achieved by carbide-forming elements such as Nb, Ti, and Mo. Inconel 625 contains 0.08 wt% carbon content, and the ductility of the Inconel 625 is less sensitive to the increase in the carbon content from the alloy F22 during the friction welding or subsequent post-wed heat treatment. Avoiding Cracking in Austenitic SS Weld Overlays Alloy 625 Overlays on Carbon Steel Cracking Metal and Welding austenitic stainless steel overlays on low alloy high carbon steel is especially difficult, because of the 22 multiplier for carbon. Cladding on alloys that have 30 points of carbon or higher, even slight increases in dilution can cause cracking. Choosing processes and parameters that minimize dilution is critical for a successful overlay.
