chain damascus

I am working with some chain as a san mai weld in a canister with some 1084 powder. Using a air/hyd jack(20 ton). after pressing a 1.5 inch tube down to .5 inches I removed the canister. There were cracks in the billet..
Would this be from pressing to cold?
First time I had this happen.
Take Care
TJ

Yep, working it too cold will cause cracks and shears. Also, don't try to move too much in one place. Take it a little slow. I've always thought a air/hydrolic jack was too slow for forging, there's others here who may think differently. I'd like to hear their opinion.
