600 and 625 Nickel/Super Alloy
Alloy 600 and 625 resists steam and mixtures of steam, air, and carbon dioxide. The alloy has excellent oxidation resistance to about 2100 °F (1149 °C). This series of alloys is well-known for its performance in extreme heat conditions—which makes each alloy variant extremely popular for use in furnace applications such as heat treating or annealing steel. These Nickel alloys are nonmagnetic, and have high strength properties, good workability, good weldability, and it is heat treatable.
