Research on the Mechanical Characteristics of a Microalloyed Steel with V in the Agreement with Environmental Trends

In this paper we studied the behavior of steel 31 VMn12 micronized with V in industrial conditions. In the experiments it was intended to obtain the mechanical characteristics corresponding to the pipe qualities, in the following states of the material: from the heat of rolling; with thermal normalization treatment; with thermal improvement treatment. Experiments have been achieved for two samples made steel and rolled into tubes F 219 x 9 mm.
