Mild Steel CR4
Materials Mild Steel CR4 (DC01)
Description
CR4 is a cold-reduced mild steel with excellent surface finish and formability, ideal for precision forming and bending applications. It is commonly used in the manufacture of automotive panels, appliances, and general sheet metal work. CR4 is not typically heat-treated but is valued for its consistent mechanical properties and suitability for painting or coating.
