4 It is principallyused in aerospace structuralparts, for internals in older,established gas turbineengines, and for a variety ofindustrial applications. Thealloy also has good wearresistance, and is used in thecold-worked condition forsome bearing and for brochure H-3057 HAYNES 188 alloy is acobalt-nickel-chromium-tungsten alloy developed as anupgrade to alloy 25. It com-bines excellent high-tempera-ture strength with very goodoxidation resistance up to about2000 F (1095 C). Its thermalstability is better than that foralloy 25, and it is easier tofabricate. Alloy 188 also haslow cycle fatigue resistancesuperior to that for most SOLID -solution-strengthened alloys ,and has very good resistance tohot corrosion.

5 It is widely usedin both military and civil gasturbine engines and in a varietyof industrial for brochure H-3001 HAYNES 230 alloy is anickel-chromium-tungsten-molybdenum alloy that com-bines excellent high-tempera-ture strength, outstandingoxidation resistance up to about2100 F (1150 C), premiernitriding resistance, and excel-lent long-term thermal 230 alloy also has lowerexpansion characteristics thanmost high-temperature alloys ,very good low cycle fatigueresistance, and a pronouncedresistance to grain coarseningwith prolonged exposure atelevated temperatures. Com-ponents of 230 alloy are readilyfabricated by conventionaltechniques, and the alloy applications for 230alloy include wrought and castgas turbine stationary compo-nents; aerospace structurals;chemical process and powerplant internals; ASME VesselCode construction; heat treatingfacility components and fixtures;steam process internals.

It is also well known inthe chemical process andpower industries, and isapproved for ASME VesselCode construction. Alloy X isone of the easiest of the SOLID -solution-strengthened alloys for brochure H-3009 HAYNES HR-160 alloy is anickel-cobalt-chromium-siliconalloy with outstanding resis-tance to high-temperaturecorrosive environments up toabout 2200 F (1205 C).

7 It alsohas good high-temperaturestrength, and good thermalstability. The resistance ofHR-160 alloy to sulfidizingenvironments, complex wasteincineration enviornments, andenvironments in many kiln andcalciner applications is un-matched by other commercialalloys. It is also well suited foruse in many chemical plant andpower plant of HR-160 alloyare fabricated by for brochure H-3129 HASTELLOY S alloy is anickel-chromium-molybdenumalloy with outstanding thermalstability combined with moder-ate strength and very goodoxidation resistance up to about2000 F (1095 C). It also hasrelatively low thermal expansioncharacteristics, and is relativelyeasy to fabricate or cast.

8 alloys has been successfully usedas a dissimilar filler metal forwelding other high-temperaturealloys. Principal applicationsinclude gas turbine seal rings,casings, and containmentstructures, as well as someindustrial usesAsk for brochure H-3003 HAYNES 625 alloy is anickel-chromium-molybdenum-columbium alloy with very goodstrength up to about 1500 F(815 C) and good oxidationresistance up to about 1800 F(980 C). Although it hasrelatively poor thermal stabilityfrom 1100-1600 F (595-870 C),alloy 625 is widely used forfabricated components in thegas turbine and aerospaceindustry, in the chemicalindustry, in the nuclear industry,and in some industrial heatingapplications.

9 Its good resis-tance to corrosion in seawater,and to a variety of aqueouscorrosive environments, alsoprovides for significant usage inmarine and pollution controlindustry environments. Alloy625 is readily fabricated, and isused as a dissimilar weldingfiller for brochure H-3073 HAYNES HR-120 alloy is aniron-nickel-chromium alloy withstrength significantly superior tocommon industrial grade iron-nickel-chromium alloys . It hasgood oxidation resistance up toabout 2000 F (1095 C), and isresistant to carburizing andsulfidizing of HR-120 alloyare easy to fabricate.
