Cory,
Thank you for your response. Yes, we have historical (30yrs) data that we developed to determine the required mechanical properties of the drawn material before cold heading to assure that the finished product meets the required mechanical standards.
I sit on a standards committee for...
Is there a formula for determining the difference in the tensile, yield, elongation and reduction of area, as measured on a cold drawn blank, from that of finished product after it has been cold headed?
We know that if the mechanical properites are measured on the cold drawn blank that these...
