edge cracking
Edge cracking signifies cracking or splitting of the edges of metal sheets or plates, most often in rolling, forming, or bending processes. It occurs because of localized excessive stress concentrations and reduced ductility at edges, contravening the integrity and quality of the finished component.
Key Features-:
- Process-induced drawbacks: Edge cracks often occur during rolling, drawing, or bending on materials with limited ductility or with destitute edge conditions.
- Material & Thickness Sensitivity: Thinner sheets and high-strength alloys are the least conditioned and aligned during forming.
It hurts the usage of metal components for manufacturing, especially those used in the automotive, appliance, and construction industries, where edge quality is the most critical factor. Optimization of process parameters, modification of material properties by heat treatment, and good edge preparation can prevent edge cracking. Early detection and control will reduce scraps, achieve consistent product quality, and maintain structural strength.
