Individual and production quantities of simulated fragments (FSPs) are shown in the pictures.Two sizes are shown: 50 caliber and 22 mm. We also make 30 caliber FSPs. Both are designed to be fired through a standard gun barrel in a lab environment to determine the effect of explosive fragments on armor panels being tested.These simulated fragments are made from 4340H steel in accordance with Mil-P-46593A which requires hardening to a 30 Rockwell hardness.The picture of the large quantity shows the fragments after an oil quench hardening process.
