State check
Separate the incoming material condition from a locally deformed surface. No universal hardness multiplier or hardened-layer depth follows from the alloy name.
Next step
For machining, check the actual grade and condition, operation, edge geometry and tool supplier's application guidance. Avoid treating every light finishing cut as an error or selecting a full-depth cut from this definition alone.
Carry the final condition into the material record
A process name does not supply a universal hardness, strength, temperature, dimensional allowance or cutting parameter.
