Studies and Research on the Influence of Carbon and Chromium Content Aimed at Obtaining Superior Mechanical Characteristics of 16CD4 Steel Used in the Automobile Industry

Abstract:

Long steel products type 16CD4 used in car industry must meet high quality conditions regarding chemical composition, surface quality, macro-structural, microstructural and mechanical characteristics. The paper presents the correlations between mechanical characteristics and the main alloying elements of 16CD4 steel; this will give varying characteristics R_m, A₅ and KCU, in correlation with the various proportions of chrome, molybdenum and carbon contained by steel. This steel brand is part of the chosen alloy steels, presenting plastic deformation resistance in conditions of high temperature. See that it is not necessary maximum carbon content for the mechanical characteristics have maximum values. The material studied was 16CD4 steel (17MoCr11), developed in EBT and treated steel to LF. Mechanical properties dependent of the content of carbon, chromium and molybdenum have been analyzed in this paper, using a mathematical model. Model verification was conducted by test Fischer and the results indicate that there are strong correlations between the mechanical properties and the percentage of carbon, chromium and molybdenum.
