Haynes 188 Strip(UNS R30188)

Haynes 188 is a cobalt-nickel-chromium-tungsten alloy with excellent high-temperature tensile strength, sulfide resistance, and oxidation resistance, allowing for long-term use at temperatures up to 1095°C (2000°F).

While Haynes 188 alloy strip cannot be age-hardened, its tensile strength and yield strength can be improved through cold working. It is also non-magnetic. It performs well in continuous high-temperature service and exhibits excellent oxidation resistance, spalling resistance, and corrosion resistance, achieved through the addition of chromium and a small amount of lanthanum. Therefore, it maintains good ductility and significantly improved strength even at low temperatures.

Strip and Foil: AMS 5608, GE B50A712, PWA 1042, Rolls-Royce MSRR 7165

Supply form: strip, foil, thickness usually ≤2 inches (about 50.8mm), supplied in solution-treated state.

Price Reference: Haynes 188 is a specialty material, and its price varies depending on specific requirements. Currently, based on international market prices, our reference price is $132 to $180 per kilogram, with a minimum order quantity of 100 kilograms. However, the final price will depend on your specific specifications (thickness/width/tolerance), purchase quantity, and required certifications (e.g., AMS 5608, MTR report).

Machining and Forming

 

This alloy exhibits good machinability and can be forged or hot-worked using conventional processes.

 

Hot Working Specifications: The entire workpiece must be heated to 1175°C (2150°F) and held at this temperature for a sufficient duration.

Cold Working and Annealing: It has good plasticity and is easy to cold-form. However, its cold-forming speed is relatively fast, and complex parts require multiple intermediate annealing processes during cold forming. All parts that have undergone hot or cold working must be solution-treated and rapidly cooled to restore their optimal properties.

Process Limitations

Prolonged annealing at temperatures below the solution temperature is not recommended, as this can lead to carbide precipitation, affecting the alloy's properties.

Note: The above process information is for reference only and is based on typical processing specifications. Actual results may vary depending on specific equipment, operating conditions, and product form. Users need to evaluate the applicability of process parameters under their specific operating conditions, and it is recommended to conduct small-scale trials before mass production. Our company makes no express or implied warranty as to the absolute accuracy of the above information or the process results.
