What are the Disadvantages of cold working
(i) Higher forces are required for deformation.
(ii) Heavier and more powerful equipment is required.
(iii) May produce undesirable residual stresses.
(iv) Not clean and scale free surfaces.
(v) Less ductility is available.
(vi) Strain hardening occurs(required immediately annealing).
(vii) More energy is required than hot working.
