Abstract

The forming behaviour of cold rolled closed annealed steel sheet in Selected samples with proper annealing and chemical composition for better formability was investigated by Erichsen Cupping test method. The results showed that the formability of cold rolled closed annealed steel having lower percentage of carbon is lesser forming property and ductility. It was found that the stress distribution and the grain density of the sheet material confirm the formability. The best combination of strength and ductile properties has steel with the low carbon and better forming property.
