(OP)
MIL-HDBK-5 says that a part in SS PH15-5 should never be used in condition A. What is the reason? Is it related to stress-corrosion cracking? Thanks, Ben bahavar

Why would you want to use a Precipitation Hardened steel in a non precipitated condition?
RE: SS PH15-5 and Cond. A in MIL-HDBK-5
The Aerospace Structural Metals Handbook (ASMH) says that the elongation in condition A is 3% minimum. Essentially for 15-5PH (and 17-4PH) condition A can be brittle, with a 180 degree bend rad of 18t.
Other data in the ASMH indicates that condition A is a bit better than conditions H900 and H925 for stress corrosion cracking and toughness.
It would pay to get the opinion of an actual metallurgist.
