Industrial rating for forging hammers

Recommended Posts

Guys- I recall reading quite a long time ago that for efficient industrial forging a hammer should have 50 # of ram weight for every 1 square inch of cross section. Does anyone else recall this recommendation and where it came from? If I had to guess I'd say old Chambersburg literature but it could have been in an old book.

I found the source finally. It comes from some Chambursburg literature on their self contained hammers. There is a table which shows that a 5000 lb hammer can work 10 inch square alloy steel on a production basis.
