Stretch-flangeability of Strong Multiphase Steels

S. Chatterjee and H. K. D. H. Bhadeshia


Stretch-flangeability measures the ability of a material to be formed into a complex shape. The parameter is often related to simple properties derived from tensile tests. An attempt is made here to discover the best way to exploit tensile test data to represent flangeabilty. It is found that the ultimate tensile strength of a steel is the single most important criterion that correlates with stretch-flangeability.
