Re: Titanium target plate???
Titanium is not used in any sort of armor that I'm aware of. Titanium is a fantasic material if strength in its range is called for but absolute lightest weight possible is needed , like is planes and space craft.
If you look at the charts , its no harder than many good heat treaded metals in fact its acctualy not as strong.
I'd take the before mentioed advise and either use it for somthing else or sell it.
Try to find some 3/8" T1 or AR500 plate , those are both designated armor materials
