Jul 10, 2008 · Steel comes in several strengths - soft, mild, medium, and hard depending on the Rockwell Hardness of each different plate's alloy. Sometimes the bullet will not pierce the steel plate - but - the plate is so hard it shatters like glass when fired straight on - but - has no effect at a slight angle. Status Resolved.
