Quarter-hard steel is a type of steel that ahs undergone partial cold-cold working to achieve a moderate level of hardness. It is more rigid than annealed steel but retains greater flexibility and formability than half-hard or full-hard steel. This balance between formability and hardness of quarter-hard steel makes it ideal for applications requiring that combination such as metal components, automotive parts, and electrical enclosures. Any application that needs additional shaping and bending during fabrication makes this type of steel the perfect fit.
