Per AMS2759/2 for heat treating steels to a minimum tensile strength of 220 ksi, tempering should start within 2 hours. If tempering cannot start within FOUR hours, a snap temper has to be given to the parts.

Subject: Time between post quench and Temper
I am interested looking into an article or book which references/states, how much maximum time one can have after post quench and start of temper on low alloy steels such as AISI grades 41L40/4140 & 43L40/4340. Anybody can help.
