METHOD FOR MANUFACTURE OF HIGH-STRENGTH MOUNTING RODS FROM CARBON AND LOW-ALLOY STEEL Russian patent published in 1997 - IPC

Abstract RU 2082769 C1

FIELD: metallurgy. SUBSTANCE: method involves conducting hot rolling to produce continuous profile of bars; providing cold deformation and simultaneously forming periodic profile by rolling with deformation extent of 17.0-40.0%; performing low-temperature annealing at temperature of 450-600 C for time period t = , where t is holding time, hour; T is annealing temperature, C. EFFECT: increased efficiency and improved quality of rods with stable mechanical properties retained during further electric contact heating.
