Stainless steel is often used in rolled strips and sheets for many metal forming operations. The hot and cold rolled sheets are subjected to annealing treatment to relieve the internal stress and eliminate any anisotropy in the alloy. The anisotropic effects in strips or sheets are reported to be highly detrimental to sheet forming and deep drawing operations. However, the annealing treatment must ensure that no recrystallized texture reappears after annealing. This paper attempts to examine the effect of sheet orientation on the fracture mechanism in the annealed sheet of AISI 202 grade alloy as an extension of earlier work. The results of microfractographic investigation are integrated to establish an empirical model of the fracture process in the alloy and explain the anisotropic effects in the ductility of the alloy as reported earlier.
