Does heat treat effect the stiffness of 4140 type material?
Does heat treat effect the stiffness of 4140 type material?
(OP)
I am trying to calculate the deflections when a 4140 bar is loaded.
Do the properties change when it is heat treated to around 35 Rc?
I am guessing I would adjust the Youngs Modulus.
any suggestions?

I would use the standard beam formula to determine deflection. In general, the geometry of the beam (cross section) will have the greatest affect on deflection.

Some alloys, like the PH grades do change modulus when aged, but not this type of material.

Corrosion never sleeps, but it can be managed.
