  • Quenching deformation in steel pipe production

    Quenching deformation in steel pipe production

    1. Residual stress and deformation: When steel is heated to about 450℃, it changes from an elastic body to a plastic body, and plastic deformation is likely to occur at this time. On the other hand, when heated to about above 450℃, the stress disappears due to the residual recrystallization. Ther...
