Abstract
Class AISI 304 austenitic stainless steels, in addition to their main characteristic (corrosion resistance), has a good limit of tensile strength, ductility and good deformation. Through a literature review about stainless steel AISI 304, this paper aims to observe and quantify its mechanical properties when exposed to a tensile test, considering the effects of temperature, speed and hardening levels that the material has when tested. It was used the engineering stress-strain diagram and the true diagram with plastic deformation velocities between 2 to 30 mm/min. and 5 to 500 mm/min. With temperatures between -253° and 27 °C, with tests done in the 20°, -10°, -30°, -50°, -166°, -80°, 0° and 27 °C. The rolling directions were between 0°, 45°, and 90° degrees. Results presented that the material was directly affected as to the variables used, but with good UTS and mechanical properties, showing tenacious, ductile, and anisotropic, with low resilience and with uncontrolled and unstable deformation when imposed at critical speeds. Having three levels of speed increment dependent on the imposed temperature and velocity, one observes as well as an apparition of martensitic farms when deformed that affected its own hardness, deformation and resistance
