Cobalt and Nickel Base Alloys |
|
|
| Use cobalt and nickel base alloys for applications involving oxidation, corrosion, metal-to-metal wear or abrasion at high temperatures. Cross-checking is a problem when applying cobalt hard surfacing alloys, especially those alloys over 40 Rc. Preheating to a temperature of 800ºF(427ºC) will eliminate this problem, as will a layer of 309 stainless or Postalloy 2866-FCO. Another possible solution is to change to Postalloy-2561-SPL, which deposits at 25 Rc and work-hardens up to 45 Rc. |
