Haynes Superalloy 188
Premium Oxidation Resistant Alloy

Haynes 188 (UNS N06188) is a cobalt-based superalloy well known for its exceptional strength, corrosion resistance, and remarkable resistance to oxidation and carburization at elevated temperatures. It performs reliably in aggressive environments where components are exposed to extreme heat and stress, making it one of the most trusted alloys in aerospace, chemical processing, and power generation industries.

Haynes 188 exhibits superior high-temperature strength, creep resistance, and stability in harsh conditions. It offers a tensile strength of up to 150 ksi, yield strength of 70 ksi, and elongation of around 50%. With excellent resistance to oxidation and carburization up to 2000°F (1093°C), combined with good thermal fatigue resistance, fabricability, and weldability, this alloy provides long-lasting performance in demanding applications.

Haynes 188 is widely used in aerospace for gas turbine components such as combustion chambers, hot section parts, and turbine blades, in industrial furnaces for heat-treating equipment, in chemical processing for reactors and heat exchangers handling corrosive media, and in power generation for steam turbine and boiler parts. It is also applied in environmental control equipment such as incinerators and flue gas treatment systems due to its ability to withstand aggressive thermal and chemical conditions.
