Haynes 188 Alloy
Common Trade Names: Haynes 188, Alloy 188, Udimet 188, Conicro 4023
Haynes 188 alloy designated as UNS R30188 is a cobalt base superalloy with a unique combination of high temperature strength and oxidation resistance, along with adequate ductility after prolonged exposure to the 1400-1600°F temperature range.
Properties:
- It is stronger than nickel-base solid-solution strengthened alloys, and far stronger than simple nickel-chromium or iron-nickel-chromium heat-resistant alloys
- Alloy 188 is readily fabricated, being welded by both manual and automatic methods including electron beam, gas tungsten arc and resistance welding.
- Strength and oxidation resistant to 2000°F
- Good post-aging ductility
- Resistant to sulfate deposit hot corrosion
Typical Applications:
- Gas turbine engine
- combustor cans
- spray bars
- flame-holders and afterburner liners
