Looking for a publication.
(OP)
I'm looking at the product data bulletin for 17-7PH steel from AK steel located here:
http://www.aksteel.com/pdf/markets_products/stainl...
I'm looking for information about welding and required post weld heat treatment and in the weldability section it ends with this line:
More information can be obtained in the
following way:
“Welding Stainless Steels,” FDB #SF-71.
I'm not finding this online or even what publication this is. Could someone point me to a source? Also, recommended post weld heat treatment for .050" thick sheet that has a crack that needs to be welded?
Thanks,
-Kirby

First, what is the heat treatment condition of the 17-7PH material??

Follow the AK Steel recommendation for heat treatment and age hardening. After welding heat to 1400 deg F to get to Condition T - austenite. Age harden at 1050 deg F to establish the T1050 in the weld region and sheet material.
You can look at trying to subject the weld region to the 1050 deg F aging treatment after welding but I think this will reduce the strength properties of the bulk sheet material.

If it is TH1050 and the properties matter than you would want to anneal it, weld, maybe re-anneal, austenite condition, and then age.
This alloy is austenitic when annealed and it welds very well.
Let me know how to send the file to you.
