tonnage requirement to compress 304 stainless steel tubing

Jacobson

Can someone tell me or tell me where to look to determine the tonnage requirement to compress 304 stainless steel tubing. I plan to use 304 SS welded tubing with .5/8" O.D. and .065" wall thickness. Working piece is 5 inches in length. I need to compress tube to height of approximately 1/4" and plan to use a flywheel press. How many tons are needed?
