Product Description

Haynes 188 Nickel Cobalt Alloy with Excellent High-Temperature Strength


HAYNES 188 is a cobalt-nickel-chromium-tungsten alloy that combines excellent high temperature strength with very good resistance to oxidizing environments up to 1095°C for prolonged exposures, and excellent resistance to sulfate deposit hot corrosion. It is readily fabricated and formed by conventional techniques, and has been used for cast component. Other attractive features include excellent resistance to molten chloride salts, and good resistance to gaseous sulfdation.


Heat Treatment of HAYNES 188
HAYNES 188 is furnished in the solution heat treated condition. Solution heat-treated at 1163-1191°C and rapidly cooled or water quenched for optimal properties. Annealing at temperatures below the solution heat-treating temperature will produce some carbide precipitation inside and may affect the alloy’s properties.
