Corodur Corolit 25 description: COROLIT 25 deposits a cobalt- based alloy with an austenitic structure. This alloy contains approximately 10,5% nickel for matrix stability during elevated temperature service. It is resistant to hot corrosion, impact, wear and extreme temperature shocks and oxidation. The alloy is machinable by hard faced tools. COROLIT 25 is used for gas turbine components, on steam and chemical valves and on equipment handling hot steel, such as tong bits, shear blades, pumps for high temperature liquids. It is suitable for use at temperatures up to 900C.
