Dear Mr. Kadambi:
At the request of Mr. Richard Kersey of Houston Lighting and Power, I'm sending you two metallurgical photomicrographs.
'Ihe ca_ stings were made per ASME SB-148. The grade is noted on the photomicrographs. To date we have only found dealloying in castings; the pipe, weld and forgings are free.
If you have any questions please contact me.
Very truly yours, Gary Se dt Materials and Quality Services GRS:nlj cc:
