Metengr,
Could you enlighten me on this:
The AUstenetizing temperature of 422 SS is 1905F. However, as we do not intend to go for that temperature in the suggested PWHT, what would be the effect on the weld material (whose chemical composition is closer to 422SS)?
(ie martensitic structure will...
Thank you for the post.
The hardness value of 20.5 HRC was obtained on the LP end area to be weld repaired. It is going to be a weld build up with SAW.
We found a supplier who can provide MTS 4Si filler wire.
We will not be able to perform the hardening process at 1877F (the recommended for...
Dear Members,
I would appreciate your comments and guidance.
We are going to perform a weld repair on a coupling fit on the LP end of a shaft made of X20CrMoV12-1 (chemically similar to 422 stainless steel). We could not find the same material here in US. Hence we are thinking of qualifying...
