Increase ductility and toughness of A514/QT100

Increase ductility and toughness of A514/QT100

Increase ductility and toughness of A514/QT100

(OP)
We are developing an automotive drive plate that requires a failry ductile and tough material.  The volume on the project is fairly low, so we are constrained to typical plate material.  A514/QT100 plate meets these requirements, but the concern is that the hardness is to high.

Can this material be tempered again to increase its ductility at a cost of some yield and tensile strengh?

Our requirements are min 70ksi Yield 85ksi Tensile with an elongation of >25%.

Of course fracture strength and crack propagation are important.
