I’m still trying to figure out how just because A vise is made out of forged steel it has more clamping power all this time I thought clamping power was determined by the thread on the spindle.
According to statistics a forged vice can be around 80.000 psi and a cast iron(weaker structure vice of same size) is about 1/3 less clamping power rating.Yes,it is possible to crack a vise.
What he was getting at was your statement: "Forged steel is loads better than cast.Has more clamping power". Just because a vise is made of forged steel does not automatically mean it has higher clamp load. That comes down to the design of the vise.
