Introduction of Incoloy825 alloy steel

Nickel alloy steel Incoloy825 (N08825) common name:
UNS N08825 (General)
Nickel Alloy 825
Alloy 825
2.4858 (material grade)

Incoloy825 (N08825) alloy steel is a corrosion-resistant alloy mainly composed of nickel, chromium, copper and molybdenum. The alloy has excellent corrosion resistance, especially in corrosive media such as strong acid, alkali and seawater. At the same time, Alloy 825 steel also has good high temperature resistance and mechanical properties, and still has high strength and plasticity at high temperatures.
