Study of creep properties of heat resistant steels

Abstract

In industrial plant the components are subjected to severe conditions of temperature and mechanical stress, the plastic deformation that continues over time. This process, called creep, occurs in petrochemical industries, power plants, and oil refineries, where its components are used for long periods of time and exposed to severe service conditions.
The objective of this thesis is to study the creep behavior of ferritic steels (1Cr 0.5Mo, 2.25 Cr 1 Mo and 5Cr 0.5 Mo), and nickel-based alloys ((Incoloy 800 (30 Ni - 20 Cr), Inconel 601 (60 Ni - 25 Cr) and steels of the HP series (25 Cr - 35 Ni) that have high thermomechanical resistance associated with the internal microstructure of the matrix.
Due to the fact that in the Fifth Interchange Conference, I present the topic of ferritic steels, in this Conference I will be presenting the topic of nickel-based alloys.
