Yes, literature is available, but looking for actual production experience as normally martensitic SS. , weld overlay is not performed.

The success of overlay depends much more on dilution control, hydrogen control, and post-weld hardness management than on the actual deposition process itself. F6NM / CA6NM is a P6, air hardening l ow carbon martensitic stainless steel with a pprox. 13%...
What problems are you expecting to face during pre and post overlay welding operations? You have not yet spelled out whether it will be Stellite, Ni based or SS based overlay and on what thickness? Could mention only the expected problems and precautions /solutions to avoid them in advance. Unless the actual welding (PQR) is done, we will not know what practical problems to face. Think you can guide us with your experience.
