Abstract
Disclosed herein is a light-gauge, ultra-high strength weathering steel sheet with a composition, material properties, and surface characteristics that make it suitable for hot-stamping applications and making hot-stamped products. Also disclosed herein is a high friction rolled carbon alloy steel strip free of prior austenite grain boundary depressions and having a smear pattern. Still further disclosed herein is a high friction rolled carbon alloy steel strip that has been surface homogenized to provide a thin cast steel strip free of a smear pattern.
