Study and investigations on experimental and finite element analysis of warm deep drawn AISI 304 stainless steel circular cup components

Abstract

Deep drawing is one of the sheet metal forming processes widely used in automobile aerospace electronics and allied industries to produce the hollow parts Presently the conventional deep drawing operation is carried out at room temperature in industries Some of the problems encountered during the conventional deep drawing operation are large deformation during deep drawing at room temperature causing problems in forming high strength low formability materials like magnesium aluminium alloys etc the occurrence of deformation induced transformation of martensite in case of austenitic stainless steel imposes the difficulty in forming operation and the major defects such as wrinkles tearing likely to occur Warm deep drawing one of the non conventional forming newlineprocesses which is performed at the temperatures above the room temperature but below the recrystallization temperature of the material is gaining importance in recent years because of its effectiveness in overcoming the above mentioned problems newline
