摘要：
Disclosed herein is a light-gauge, ultra-high strength weathering steel sheet comprising between 0.5% and 1.5% nickel. Also disclosed herein is a high friction rolled carbon alloy steel strip free of prior austenite grain boundaries 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.
