Abstract
Thin stainless steel sheet has been widely used for the small sized and high strength mechanical parts. The materials are initially experienced either the TA (Tension Annealing) or heat treatment after cold rolling, then processed for the final products. Not only stainless steel but thin sheet materials basically have anisotropy in their physical and mechanical properties because of unidirectional rolling history. A few results were reported on the effect of the annealing temperature on those properties. In this paper, the effect of temperature annealing in the air on the anisotropy of mechanical properties of stainless steel thin sheet such as surface roughness, W-bending, Vickers hardness, Young's modulus, spring bending elastic limit and pulley-bendingtype fatigue limit were described.
