B50A947A4 Material

[BoltSlinger]

Anyone know anything about B50A947A4?
I believe it is a 400 series stainless.
I know B50A951A1 Stainless 422

Thanks ahead of time for any help on this.

This is GE material designation.

I thought that. I can only find one thing online that mentions the chem of it. I can not find a full GE write up specification.

Having worked with GE Large Steam Turbine repair shops and field personnel as an owner/user over many years I don't have access to help you directly. I looked over my old notes and can't locate this particular material designation. In addition, GE material specifications can require very specific heat treatment and NDT requirements for service that a simple chemical composition identification were to provide.
