Steel for plastic shaping cold and heat treatment, this deformation

摘要

P steel, to a cold plastic shaping. / p & & p & a steel of high mechanical strength, suitability for shaping is cold, is obtained by subjecting a hardened steel has a rapid heating by induction has a high frequency, and then cooling, and then has a rapid heating by induction heating has a high frequency at a temperature comprised between 300 and 600c, then has a rapid cooling. This steel may be carried out a cold, and then be heated again at a temperature comprised between 300 and 500c for 30 to 60 minutes, so as to obtain a steel having an elastic limit high. / p & & p & application for the preparation of the steels quenching in cold shaping. / p
