Carbon and Low-Alloy Steel Plate

The production and use of steel plate is aided by a system of standard designations and associated specifications defining composition, property, and performance ranges. This article contains an extensive amount of information on the designations and grades of plate products and how they are made. Although most steel plate is used in the hot-finished condition, some applications require one or more heat treating steps to mitigate imperfections and/or improve relevant qualities. The article discusses these interconnected factors as well as their impact on mechanical properties and critical fabrication issues, including formability, machinability, and weldability.
