  • Method of producing high-strength rods of austenitic steel and a rod produced by such method
    Patent number: 10046374
    Abstract: Rods with the transverse cross-section surface area of at least 150 mm2 and tensile strength UTS above 1200 Mpa is produced using a plastic deformation that consisted of one-pass hydrostatic extrusion of the billet 1 made of austenitic steel, with the initial temperature of the billet being below 100° C. The reduction R of the transverse cross-section surface area of the biller (1), which takes place during the extrusion, is at least 2.
    Type: Grant
