Microstructural and Mechanical Characterization of Steel 2, 25Cr-1Mo Treated by Quenching Process

Cr-Mo family steels are widely applied in the petrochemical industry, subjected to creep, may have their mechanical properties degraded in service, undergoing changes in their microstructure, therefore, understanding the heat treatment routes of these materials is of great relevance to good mechanical performance is obtained. This research aimed to investigate the influence of Quenching heat treatment on the microstructure and mechanical properties of the 2.25Cr-1Mo steel. For this, specimens were heated to 1,223 K in an argon atmosphere for 2 h and cooled in mineral oil. The microstructural characterization showed a predominance of the martensitic phase
