Vice psi questions?

I just bought a new Yost 865-di vice for several reasons. One being that it's made in the USA. While doing research on vices, a lot of them are 30,000 psi, where this one is 65,000 psi ductile iron (hence the "di" in the model#). What's the difference/significance of this?
Will it be stronger than a 30?
Less flex? Ie. - off center clamping or clamping a taper.
The anvil will take more of a beating?
Will this crack/chip easier?

One of the advantages was a lifetime warranty vs a year on some others, plus it's made in the USA.

Fwiw, I almost had a C. Parker vice from 1903 and a Wilton instead of this, but the ***** backed out after I drove an hour. That's actually how I found this site.

Ttyl, Fahn

It's just a higher grade iron.

The rating is the yield strength of the material, and while that material will also have other attiributes, without more information, I'm not sure what those would be for sure. I would ASSUME it would flex less and be harder and possibly easier to chip, but that's a guess.

What the rating means is that it can be placed under tensile loading and will not permanently deform unless that load causes any internal cross section of the vise assembly to see more than 65,000 psi. Anything above that may result in a permanent bend or breakage.

I would strongly suggest not beating on the anvil or any other part of the vise if it were me. I've read here a lot that's the main reason for vises breaking. Find something else to beat on if you can. Or a junk vise to beat on.

Whilst I don't use a hammer on a vise, the ductile ones can take it fairly well.
View media item 64793Vises are made for using and the OP has bought a new one so its a bit different than someone finding a tea nice old one and then beating on it.
