Except for the minimising contact between the metal and any sources of atomic hydrogen, what are all the other methods we can adopt while 3D printing (DED methods) stainless steels?

Best regards
Thicker materials with higher carbon content are often more likely to experience this kind of stress corrosion. If hydrogen absorption is expected to occur during service, lower carbon steels might be considered. Penflex offers L-grade stainless steels—like 316L—in such circumstances.
Baking metals are a common means of removing hydrogen during the manufacturing process as is avoiding quick changes in temperature that might lead to condensation. It’s also important to keep hose assemblies off the ground and protected from exposure to chemicals that might lead to corrosion and premature failure
Hi,
Hope these papers help you, if you could find the method included:
