You can determine the minimum hardness by using the minimum specified tensile strength, then converting it to hardness per ASTM A370. Remember the conversion is only considered an estimate.

Subject: Minimum hardness on low alloy metals
I am doing site inspection for hardness on high temperature low alloy tubes . There are references for the maximum allowable hardness, but where can I find the minimum allowable hardness value preferably in Vickers on materials such as T12,T22?
