METHOD FOR PRODUCTION OF PIPES FROM AUSTENITIC CORROSION-RESISTANT STEELS

摘要

A method for production of pipes from austenite corrosion-resistant steels comprises the non-expandable cold polling with heat treatments on intermediate and ready sizes which is carried out at temperature of 1160-1230 °С and the soakings, providing formation of microstructure with quantity of large angular special low-energy borders of grains oftype not less than 65 %.
