t~ormability of sheet steel in stamping operation primari b depends on strain hardening exponent Ink average plastic strain ratio I~J and the maximum strain the material can undergo before the onset of localized necking. The formabitity parameters(n and rJand the forming limit diagrams have been evaluated for a variety of sheel steel products, extensively used for press forming of components of diverse shapes e.g. extra deep drawing quality auto-body sheets, high strength cold rolled sheets, LPG steel for gas cylinders, austenitic and ferritic stainless steels, etc. The effect of sulphide shape control on tormability of hot rolled HSLA steel has also been studicd. Additionally, the press performance of auto-body sheets and austenitic stainless steels have been monitored and e~aluated at customer's end for complete information on the formability.
