Forecasting the Mechanical Properties of Heat Treated Pipes by Computer Modeling in Deform 3D

Abstract

In this work, the results of research the structure of heat-treated low-alloy steel 13CrV
using the Deform 3D HT program, which allows to determine the optimal technological parameters
of the steel hardening process. In addition, at the research, experiments were conducted in which it
was found that the optimal mode of pipes heat treatment to obtain a strength group corresponding to
the level of Q125 according to the API 5CT standard is thermocyclic quenching with low tempering
at a temperature of 150 ◦ C at which a metal structure is formed the martensite phase in an amount
of more than 85 %.
