ABSTRACT:

This paper studies the durability of hot rolled steel alloys, AISI 1024 and AISI 304, considering their application in components of the solid waste industry. Through the analyse of the intrinsic manufacturing defects, microhardness and fatigue study with and without corrosion results, is presented a new approach to determine the durability of two steel alloys based on fatigue limit stress prediction models. For the study of the effect of the corrosion the test specimens to obtain the S-N curves were submitted to organic waste for 48 hours.
