Haynes International alloys are used by many markets to solve industrial problems.
Examples of other markets include:
HASTELLOY® B-3® alloy
HASTELLOY® B-3® exhibits extremely high resistance to pure hydrochloric, hydrobromic, and sulfuric acids. Furthermore, it has greatly improved structural stability compared with previous B-type alloys, leading to fewer concerns during welding, fabrication, and service.
HASTELLOY® C-22® alloy
HASTELLOY® C-22® alloy is one of the well-known and well-proven nickel-chromium-molybdenum materials, the chief attributes of which are resistance to both oxidizing and non-oxidizing chemicals, and protection from pitting, crevice attack, and stress corrosion cracking. Its high chromium content provides much higher resistance to oxidizing media than the family standard, C-276 alloy, and imparts exceptional resistance to chloride-induced pitting, an insidious and unpredictable form of attack, to which the stainless steels are prone.
HASTELLOY® C-276 alloy
HASTELLOY® C-276 alloy is the first wrought, nickel-chromium-molybdenum material to alleviate concerns over welding (by virtue of extremely low carbon and silicon contents). As such, it was widely accepted in the chemical process and associated industries, and now has a 50-year-old track record of proven performance in a vast number of corrosive chemicals.
HASTELLOY® C-2000® alloy
HASTELLOY® C-2000® alloy is unique among the versatile nickel-chromium-molybdenum materials in having a deliberate copper addition. This provides greatly enhanced resistance to sulfuric acid. It also has a high chromium content, to maximize its resistance to oxidizing chemicals and process streams contaminated with ferric ions and dissolved oxygen.
HASTELLOY® G-35® alloy
HASTELLOY® G-35® alloy was developed to resist “fertilizer-grade” phosphoric acid (P2O5), which is used in the production of fertilizers. Tests in real-world solutions indicate that G-35® alloy is far superior to other metallic materials in this acid. It was also designed to resist localized attack in the presence of chlorides, since this can be a problem beneath deposits in evaporators used to concentrate “fertilizer-grade” phosphoric acid. Furthermore, G-35® alloy is much less susceptible to chloride-induced stress corrosion cracking than the stainless steels and nickel-chromium-iron alloys traditionally used in “fertilizer-grade” phosphoric acid.
HASTELLOY® N alloy
HASTELLOY® N alloy has good resistance to aging and embrittlement and good fabricability. It has excellent resistance to hot fluoride salts in the temperature range of 1300°F to 1600°F (705°C-870°C).
ULTIMET® alloy provides many of the corrosion characteristics of the nickel-based HASTELLOY® G-type alloys and many of the wear characteristics of the cobalt-based STELLITE® alloys, in a single, highly weldable material. It excels under conditions conducive to galling and cavitation erosion.
HAYNES® 214® alloy
HAYNES® 214® alloy is a nickel-chromium-aluminum-iron alloy designed to provide the optimum high-temperature oxidation resistance for a wrought material, while at the same time allowing for conventional forming and joining. This alloy offers outstanding oxidation resistance to 2300°F (1260°C) and is used in demanding, specialized gas turbine parts, such as honeycomb seals combustor splash plates and other static oxidation-limited parts.
HAYNES® 230® alloy
HAYNES® 230® alloy is a nickel-chromium-tungsten-molybdenum alloy that offers the best combination of high- temperature strength, resistance to oxidizing environments up to 2100°F (1149°C) for prolonged exposures, excellent long-term thermal stability, and fabricability of any major high-temperature alloy. It is used for combustion cans, transition ducts, flame holders, thermocouple sheaths, and other important gas turbine components.
HAYNES® 282® alloy
HAYNES® 282® alloy is a new, wrought, gamma-prime strengthened superalloy developed for high-temperature structural applications, especially those in aero and industrial gas turbine engines. It possesses a unique combination of creep strength, thermal stability, weldability, and fabricability not found in currently available commercial alloys. This new alloy has excellent creep strength in the temperature range of 1200 to 1700°F (649° to 927°C), surpassing that of Waspaloy alloy and approaching that of R-41 alloy. The features of this alloy make it suitable for critical gas turbine applications, such as sheet fabrications, forged rings and cases, exhaust and nozzle structures, and other hot-gas-path components.
HAYNES® 556® alloy
HAYNES® 556® alloy is a high-strength alloy with broad spectrum of resistance to high-temperature corrosive environments. Used in waste incineration, heat-treating, calcining, chemical processing, galvanizing, refinery, boiler and gas turbine components of various types. Excellent fabricability and excellent as a dissimilar filler metal for welding nickel or cobalt alloys to iron-base alloys.
HAYNES® 617 alloy
HAYNES® 617 alloy is widely used in gas turbines for combustion cans, ducting and transitions.
HAYNES® 625 alloy
HAYNES® 625 and 625SQ® alloys are used in wide variety of aerospace components. The 625SQ® alloy grade offers improved LCF properties for bellows type applications.
HAYNES® HR-120® alloy
HAYNES® HR-120® alloy offers very good creep strength to 1800°F (980°C), together with good resistance to several industrial environments (e.g. excellent carburization and very good sulfidation and oxidation resistance). This economical alloy has found use in large frame engine shrouds, as well as use in heat treating fixture and industrial heating applications as an upgrade from 330 alloy, 800H alloy and stainless steels.
HAYNES® HR-160® alloy
HAYNES® HR-160® alloy has outstanding resistance to sulfidation and other high-temperature aggressive environments. Used in waste incineration, boiler, high-temperature reaction vessel and rotary calciner applications.
HAYNES® HR-224® alloy
HAYNES® HR-224® HAYNES® HR-224® is new alloy with excellent oxidation resistance to 2200°F (1204°C), with improved fabricability and weldability compared to HAYNES® 214® alloy. Used in demanding industrial heating applications and steam reformer parts.
HAYNES® HR-235® alloy
HAYNES® HR-235® is a high-chromium, copper-bearing nickel alloy that has excellent resistance to metal dusting in carbonaceous high-temperature environments. Potential uses include applications in petrochemical production and syngas plants. Similar to other nickel-based corrosion resistant alloys, the alloy is readily fabricated and welded.
HASTELLOY® X alloy
HASTELLOY® X alloy is a nickel-chromium-iron-molybdenum alloy that has been in service in aerospace applications for nearly 50 years. The alloy offers very good balance of high-temperature strength, oxidation resistance, and fabricability. This alloy is widely used for aircraft and industrial gas turbine engine fabricated combustor and exhaust components, such as transition ducts, combustor cans, spray bars and flame holders, afterburners, and tailpipes.
