Alloy 188 : The Ultimate Solution for High-Temperature and Corrosive Environments
Introduction
In industries where extreme heat, corrosive gases, and mechanical stress converge, material selection becomes critical to operational success. Alloy 188, a cobalt-based superalloy developed to thrive in these punishing conditions, has emerged as a cornerstone material for aerospace, energy, and chemical processing sectors. Shanghai Fanchuang Special Alloys, a leader in advanced alloy manufacturing, provides high-performance Alloy 188 products engineered to meet the rigorous demands of modern industrial challenges.
Key Advantages of Alloy 188
Outstanding High-Temperature Performance
Alloy 188 retains exceptional tensile and creep strength at temperatures up to 1800°F (982°C), outperforming many nickel-based alloys. Its ability to resist deformation under prolonged thermal stress makes it ideal for gas turbine combustion chambers, afterburner components, and exhaust systems.
Superior Oxidation and Sulfidation Resistance
The alloy’s optimized composition—22% chromium, 14% tungsten, and trace lanthanum—creates a protective oxide layer that shields against oxidation, sulfidation, and carburization in aggressive environments like coal gasification and petrochemical processing.
Enhanced Fabricability
Unlike brittle alternatives, Alloy 188 maintains excellent ductility for machining, welding, and forming, reducing production costs and enabling complex geometries in heat exchangers and industrial furnace components.
Long-Term Durability
With minimal phase degradation over time, Alloy 188 ensures extended service life in applications such as nuclear reactor components and aerospace fasteners, significantly lowering lifecycle costs.
Applications of Alloy 188
Aerospace: Combustion liners, turbine seals, and rocket engine nozzles.
Energy: Gas turbine hot sections, heat recovery systems, and burner nozzles.
Industrial: Chemical processing equipment, furnace fixtures, and waste incineration systems.
