The stainless steel has a wide uses in engineering industry because of his geometric properties, such as resistance corrosion, high flexibility, appropriate hardness, and its ability to tolerate static and dynamic loads. And it is a very suitable in domestic uses and in manufacturing some of automotive parts and in many engineering applications. In this research a sample of stainless steel type 304 was selected, where heat treatment (Normalizing) was carried out for him, this process was carried out at (1150, 1100, 1150 ) C0 respectively, after that tempering process was carried out at 350 so as to remove the internal stresses and to prevent carbides precipitation which occurs at a temperature of (450-800) C0 for the stainless steel, also mechanical tests were carried out, which is tensile and hardness tests using Brinell method, in addition to that a fatigue and wear testing, also tear and shock testing using Sharbi method, in general the experimental results showed that the thermal treatment leads to improve the mechanical properties with the exception of the shock testing, and the best cases appeared at 1100 C0.
