Why Does Spheroidizing Annealing Make Steel Strip Easier to Bend?

In the manufacturing of steel strip—especially high-carbon steels such as C75S, SK5, 65Mn, and alloy grades—spheroidizing annealing is one of the most important heat-treatment processes. It is widely used before cold forming, stamping, bending, or deep drawing, because it significantly improves the material’s ductility and workability. But why does spheroidizing annealing make steel strip easier […]
