Finishing wire rolling method for reducing the duplex grain structures in 304H stainless steel wire

摘要

The present invention relates to a wire rod finish rolling method for maximally suppressing the generation of the mixed structure in the manufacturing process of 304H stainless steel wire, which is heated by heating the 304H stainless steel billet in the heating furnace 5.5 through the rough rolling → medium rolling → finishing rolling In manufacturing the mmφ wire, the rolling temperature at the time of finishing rolling is 770 ° C. to 870 ° C., and the true strain in the cross section of the wire is rolled so as to be 0.2 to 0.85 in the final rolling pass.;304H stainless steel, wire rod, spring, true strain rate, finish rolling
