Abstract
564,549. Alloys. FAIRWEATHER, H. G. C. (United Drill & Tool Corporation). Dec. 16, 1942, No. 17909. [A Specification was laid open to inspection under Sect. 91 on May 10, 1943.] [Class 82 (i)] [Also in Group XXII] Wire of carbon and high speed steel, nickel, chromium, molybdenum and other non-austenitic alloy steels are drawn at a temperature above 900‹ F., but appreciably below the lower critical temperature, with a relatively large reduction of area at each stage. For carbon tool steel or high speed steel the temperature range is 1000 to 1100‹ F., and the area reduction is about 40 per cent per die. The steel may contain 0.9 to 2.5 per cent carbon, and upwards of 0.5 per cent chromium and 0.25 per cent vanadium; or 0.6 to 1.5 per cent carbon with 4 to 16 per cent molybdenum or 4 to 24 per cent tungsten ; or 0.9 per cent carbon and 0.5 to 5 per cent nickel or 0.5,to 1.5 per cent chromium or 0.1 to 0.5 per cent molybdenum or vanadium. The steel may be of the stainless type or may contain upwards of 7 per cent cobalt or 3 per cent vanadium. The rod is coated with graphite, or other lubricant capable of withstanding the temperatures, as by passing it through a suspension of graphite in distilled water prior to heating, preferably effected by passing through a small induction heating coil placed close to the die. The wire may be reduced from 0.281" diam. to 0.065" in six stages without any intermediate annealing or pickling.
