Material Notes:
Universal No. 6 is a cobalt-chromium-tungsten alloy suited for applications requiring extreme impact resistance at elevated temperatures, exhaust valve contact surfaces, hot and cold trimmer dies and pump shafts are some examples of No. 6 uses. Hardness characteristics remain intact under operation temperatures to 1500°F. The excellent resistance to impact and high temperatures allow Universal No.6 to be used in severe applications where a hardness of Rc 40 - 47 is required.Machinability: Use carbide tools.Information provided by Universal Wire Works for their line of welding wire and filler metal.
