Postalloy® 2804-FCG

Postalloy® 2804-FCG is a flux-cored, nickel base alloy designed for hot-working hardfacing applications, such as rotary dies and flat open face dies. Postalloy® 2804-FCG is alloyed with chromium, molybdenum, tungsten and cobalt. The deposits withstand stresses and oxidation at elevated temperatures up to 2000 °F (1100 °C). Postalloy® 2802-FCG is recommended as an underlay.
