Repair Welding - an overview | ScienceDirect Topics

Problems may arise in the repair welding of machinery and parts due to high carbon content and high impurity levels, and such conditions demand the use of a weld metal that can accommodate dilution without solidifiion cracking and has a low hydrogen potential. The compositions frequently used for this purpose are 20Cr–9Ni–3Mo, 23Cr–12Ni (type 309), 22Cr–12Ni–3Mo and 29Cr–9Ni.
