Abstract

This work carried out a study of the mechanical properties of two common steels used for the manufacture of cold drawing welded steel tubes, SAE 1012 and ST-52.3. The tubes were submitted to chemical and thermal treatment and then were drawn. Properties such as hardness and tensile strength had been evaluated in each stage of the process. Incremental reductions of 5% were made in the tube in order to investigate the behavior of its properties. An estimation of the maximum reduction allowed without necessity of intermediate annealing for two models, considered for Sachs and Baldwin, and another one for Backofen were also discussed. Equations obtained from the curves will be the base to estimate the final properties desired for a specific reduction of the tube. They will also help in the selection of different steels, by making a relation between reduction and its properties.
