(OP)
Could someone please let me know where I can find micro etching solutions and photo micrograph of grain structure for solution annealed Custom 455 stainless steel?

RE: Micro Etchants for Custom 455 Stainless Steel

Check this article:

"Ralph's is usually best for the precipitation hardenable stainless steels; however, Vilella's reagent will work fine if a light etch is preferred. Etching time will vary because the alloy in the aged condition will react quicker to the etchant. The higher the aging temperature, the quicker the response. An alloy aged at 1100°F (590°C) will etch darker and quicker than one aged at 900°F (480°C)."

There's info on etchants and micrographs of similar alloys.
