What Is Cold Reduction?

Cold Reduction

Cold reduction is a metalworking process used to reduce the thickness of steel by passing it through rollers at room temperature, below its recrystallization point. This process strengthens the steel through strain hardening, resulting in a more uniform thickness, improved surface finish, and enhanced mechanical properties compared to hot-rolled steel. Cold-reduced steel is often used in applications that require precise dimensions, smooth surfaces, and higher strength, such as automotive parts, appliances, and metal furniture.
