20 Cr-19 Ni- 6.5 Mo Heat treatment
20 Cr-19 Ni- 6.5 Mo Heat treatment
(OP)
Is it possible to heat treat such a high alloyed stainless grade? If so what is the best heat treatment route for this grade? At present I believe it goes through a re-melting route. Is it possible to heat treat without getting signifigant scalling/catastrophic oxidation? Any comments greatly appreciated. SS

If you anneal in air you must have plenty of fresh air or you risk catastrophic oxidation. Proper pickling is critical.
It is usually better to anneal in dry hydrogen, but getting a fast enough quench rate in bright anneal may be difficult.
Why do you want to heat treat? have you done lots of welding or forming?
