Universal Cobalt Alloy No.6 |
||
| Description: | 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 alloy Universal No.6 to be used in severe applications where a hardness of Rc 40-47 is required. Universal No.6 is designed to give excellent results on applications requiring erosion, corrosion, cold abrasion and oxidation (1100-1500 F) resistance. Applications with hot abrasion or impact will yield fair to good results. |
