Carbon Steel, Stainless Steel & Aluminum
Part 1 Carbon Steel
Part 2 Stainless Steel & Aluminum
The Department of Materials Science and Engineering at Ohio State University using methods, tooling, and a testing machine of their design, generally referred to as the OSU Formability Test, were sponsored by the Industrial Perforators Association to evaluate the capacity of various types of perforated carbon steel, stainless steel and aluminum as to their formability. The tests, performed first on carbon steel and then on stainless steel and aluminum, are presented below under Part I and Part II respectively.
For each test the measure of formability was the punch height at which the material sustained a maximum load was obtained from the recorded load versus displacement data. Three tests were performed on 94 carbon steel and 90 stainless steel and aluminum samples. The average punch height was recorded
as the test result.

The OSU testing machine shown here in three steps of the test.
Step 1
The 1” radius-punching tool withdrawn with the test sample above it.
Step 2
The test sample clamped in position.
Step 3
The punching tool advanced at a rate of 1mm/sec until failure.
