I'm not sure you can bring the hardness of 410 martensitic steel down to 160HB.
A473 type 410 sheets have a hardness above 200 (nominally 220).
Let's see if other colleagues have any experience with this.

My customer is given TDC for annealing at 955 C but raw material supplier is suggesting that they do only with 850 C. Its not for fabrication, to give raw material into finished component by machining. Required hardness is 160 BHN
As per ASTM A473, Grade/Typ. 410 can be supplied as per the following conditions:
Condition A refers to annealing. (ASTM A473 mentioned with A, 1,2,3,). In this case how to determine the Annealing temperature?
My requirement is to get hardness of 160BHN
