Haynes 188 (UNS R30188) is a cobalt-nickel-chromium-tungsten alloy with excellent high temperature strength. Haynes 188 can be processed by conventional techniques. Haynes 188 has excellent resistance to molten chloride salts and good resistance to gaseous sulfidation.

HAYNES 188 EASY WORKLESS

Haynes 188 alloy has good forming and welding properties. If kept at a temperature of 2150 ° F (1175 ° C) for a time sufficient to bring the whole component to a temperature, it may be forged or otherwise hot. As a result of the ductility property, Haynes 188 can be easily processed with cold processing. However, Haynes 188 hardens rapidly; therefore, complex annealing operations may require frequent annealing operations.

Haynes 188 can be welded by manual and automatic welding methods including gas tungsten arc (TIG), gas metal arc (MIG), electron beam and resistance welding. Haynes 188 exhibits a good retaining source.

HAYNES 188 USAGE AREAS

Haynes 188 is used in the production of high temperature working parts in the aviation industry. The Haynes 230 alloy is an improved and new version of the Haynes 188 alloy and has been replaced by Haynes 188 in practice.
