Haynes® 25

Properties of Haynes® 25

Haynes® 25 combines mechanical strength at high temperatures with chemical resistance in oxidative and sulfurous environments. The addition of tungsten increases creep and tensile strength, while cobalt and nickel provide structural stability and toughness, even under prolonged thermal stress.

The alloy is resistant to sulfidation, making it suitable for applications where standard alloys would quickly degrade. Furthermore, Haynes® 25 is easily weldable, forgeable, and formable, and suitable for sheet, casting, and bar production.

Its resistance to galling makes it a reliable choice in applications where metals come into contact under pressure and friction.

Applications of Haynes® 25

Haynes® 25 is used in applications where extreme heat, chemical aggression, and structural reliability are crucial. Examples include:

• Cast components for high-temperature applications

• Gas turbines, including combustion chambers and turbine parts

• Industrial furnaces and heat treatment equipment

• Aircraft engines and exhaust systems

• Chemical processing equipment in sulfur-containing environments

Thanks to its durability and versatility, Haynes® 25 is a favored material in the aerospace, power generation, and heavy industries.

Haynes® 25 is the alloy of choice for demanding applications where heat resistance, sulfidation resistance, and mechanical strength converge.
