Since

most of the previous studies were focused on the enhancement of the

mechanical properties of steel by either
heat treatment or mechanical

treatment
therefore the present work is concerned on the study of

tensile and creep
properties of stainless steel 304 under the effect of

both heat and mechanical
treatment which

In

the prese
nt work stainless steel 304 has been tensile tested until

fracture at
different temperatures (RT 200 C 300C 400C 500C 570C 600C

)

For determining the tensile properties such as

according to the variation of

ultimate tensile strength with temperature for the
tested steel at the

above mentioned temperatures the thermo
