Well that's the whole point. Any mill can make steel to the required specifications, but to turn it into armor plate, it must be heat treated, then tempered.

Then, it must be fabricated into the required shapes, an operation requiring very special tools on hardened steel.

Did you even read the info on Clifron's website?

I don't think so. I think the mills need to meet certain criteria in order for the DoD to approve them during the bidding process.

I know, I've worked in Machine shops and have worked with tool steel and the like.
