I would start with AvestaPolarit, as I know they produce high chromium duplex stainless steel grades like 2205 & 2507. You can find more information using the following link:
I am not sure what you mean by forged 22 Cr. Do you mean that you want your final part/component to be forged from duplex stainless steel? Or do you mean for the raw material to be a wrought processed rod/bar/plate instead of casting ingot?
