As microestruturas e propriedades mecânicas dos aços inoxidáveis austeníticos, ferríticos e martensíticos que definem a utilização de cada um: uma revisão de literatura

Abstract

After the Iron Age, steel became synonymous of contemporaneity and beauty in European cities. The two world wars, all society has seen an enormous technological advance. In this context, the existing steel began to be further studied and developed. In 1913 stainless steels were created, characterized by their bright color and corrosion resistance, this material has also become an object of study and has gained a lot of popularity in society with different types of chemical composition, properties and different applications. Given this context, this work aims to analyze the microstructures and mechanical properties of AISI 304 stainless steels. AISI 430 and AISI 420, as well as make a comparison between them. The work was carried out based on the existing literature, where the data collected from existing research were related. With the research carried out, many works were identified that converged on the same data obtained among themselves and also with other existing literature. It was found that the AISI 420 has the best mechanical resistance among the others, the AISI 430 has the lowest cost and it was concluded that the heat treatments are of essential importance to obtain desired mechanical properties in the material.
