Forming & Forming & BendingUseful Fabrication InformationBendingMany plate applications require that the steel be formedto varying extents ranging from simple cold Bending in apress brake to deep drawing in complex, multi-stage diepresses. The latter is a specialist process outside thescope of this note, however, the metallurgical principlesinvolved and some general guidelines appropriate to themore conventional forming operations are chemical composition, mechanical properties,metallurgical microstructure, surface condition,thickness, edge condition, and forming direction inrelation to the rolling direction of the steel, will have aninfluence on the plate forming Forming involves plastic deformation, or stretching,of the material surface on the outside of the bend.
For most structural applications, the extent of strain hardening and consequent increase in strength with reduction in toughness and ductility resulting from cold
