Product Description

 Chemical composition of haynes 230



















































Principal Features of haynes 230

Excellent High-Temperature Strength, Thermal Stability, and Environment Resistance
Haynes 230 alloy is a nickel-chromium-tungsten-molybdenum alloy that combines excellent high temperature strength, outstanding resistance to oxidizing environments up to 2100°F (1149°C) for prolonged exposures, premier resistance to nitriding environments, and excellent long-term thermal stability. It is readily fabricated and formed, and is castable. Other attractive features include lower thermal expansion characteristics than most high-temperature alloys, and a pronounced resistance to grain coarsening with prolonged exposure to high-temperatures.

Easily Fabricated of haynes 230
Haynes 230 alloy has excellent forming and welding characteristics. It may be forged or otherwise hot-worked, providing that it is held at 2150°F (1177°C) for a time sufficient to bring the entire piece to temperature. As a consequence of its good ductility, 230 alloy is also readily formed by cold-working. All hot- or cold-working parts should be annealed and rapidly cooled in order to restore the best balance of properties. The alloy can be welded by a variety of techniques, including gas tungsten arc (GTAW), gas metal arc (GMAW), and resistance welding.

Heat-Treatment of haynes 230
Wrough 230 alloy is furnished in the solution heat-treated condition, unless otherwise specified. The alloy is solution heat-treated in the range of 2150 to 2275°F (1177°C) and rapidly cooled or water-quenched for optinum

properties.Annealing at temperatures lower than the solution heat-treating temperatures will produce some carbide precipitation in 230 alloy, which may marginally affect the alloy's strength and ductility.

Casting of haynes 230
Haynes 230 alloy may be cast using traditional air-melt sand mold or vacuum-melt investment casting foundry practices. Silicon levels at the high end of the specification range are recommended for enhanced fluidity. Castings may be used in either the as-cast or solution-heat-treated condition depending upon property requirements.

Applications of haynes 230
Haynes 230 alloy combines properties which make it ideally suited for a wide variety of component applications in the aerospace and power industries. It is used for combustion cans, transition ducts, flameholders, thermocouple sheaths, and other important gas turbine components. In the chemical process industry, 230 alloy is used for catalyst grid supports in ammonia burners, high-strength thermocouple protection tubes, high-temperature heat exchangers, ducts, high-temperature bellows, and various other key process internals.
In the industrial heating industry, applications for 230 alloy include furnace retorts, chains and fixtures, burner flame shrouds, recuperator internals, dampers, nitriding furnace internals, heat-treating baskets, grates, trays, sparger tubes, thermocouple protection tubes, cyclone internals, and many more.

Creep and Stress-Rupture Strength

Haynes 230 alloy is a solid-solution-strengthened material which combines excellent high-temperature strength with good fabricability at room temperature. It is particularly effective for very long-term applications at temperatures of 1200°F (649°C) or more, and is capable of outlasting stainless steels and nickel alloys by as much as 100 to 1 depending upon the temperature. Alternatively, the higher strength of 230 allows for the use of design section thickness as much as 75 percent thinner than lesser alloys with no loss in load-bearing capability.



Haynes 230 alloy is readily welded by Gas Tungsten-Arc (TIG), Gas Metal-Arc (MIG) Shielded Metal-Arc (coated electrodes), and resistance welding techniques. Its welding characteristics are similar to those for Hastelloy X alloy. Submerged-Arc welding is not recommended as this process is characterized by high heat input to the base metal and slow cooling of the weld. These factors can increase weld restraint and promote cracking.
Base Metal Preparation
The joint surface and adjacent area should be throughly cleaned before welding. All grease, oil, crayon marks, sulfur compounds and other foreign matter should be removed. It is preferable, but not necessary, that the alloy be in the solution-annealed condition when welded.
Filler Metal Selection
Haynes 230-W filler wire (AWS A5.14, NiCrWMo-1) is recommended for joining 230 alloy by Gas Tungsten-Arc or Gas Metal-Arc welding. Coated electrodes of 230-W alloy are also available for Shielded Metal Arc welding in non-ASME code construction. For dissimilar metal joining of 230 alloy to nickel-, cobalt-, or iron-base materials, 230-W filler wire, Haynes 556 alloy, Hastelloy S alloy (AMS 5838) or Hastelloy W alloy (AMS 5786, 5787) welding products may all be considered, depending upon the particular case. 
Preheating, Interpass Temperatures and Post-Weld Heat Treatment
Preheat is not usually required so long as base metal to be welded is above 32°F (0°C). Interpass temperatures generally should be low. Auxiliary cooling methods may be used between weld passed, as needed, providing that such methods do not introduce contaminants. Post-weld heat treatment is not normally required for 230 alloy.


Haynes 230 alloy is similar in machining characteristics to other solid-solution-strengthened nickel-based alloys. As a group these alloys are classified as a moderate to difficult ot machine; however, it should be emphasized that they can be machined using conventional methods at satisfactory rates. As these alloys will work-harden rapidly, the keys to successful machining are to use slower speeds and feeds, and to take heavier cuts than would be used for machining stainless steels.

  • 1. SCEA-Side cutting edge angle, or lead angle of the tool.

  • 2. At any point where dry cutting is recommended, an air jet directed on the tool may provide substantial tool life increases. A water-base coolant mist may also be effective.

  • 3. Oil coolant should be a premium quality, sulfochlorinated oil with extreme pressure additives. A viscosity at 100°F of from 50 to 125 SSU is standard.

  • 4. Water-base coolant should be a 15:1 mix of water with either a premium quality, sulfochlorinated water soluble oil or a chemical emulsion with extreme pressure additives.

  • 5. Water-base coolants may cause chipping or rapid failure of carbide tools in interrupted cuts.

  • 6. M-40 series High Speed Steels include M-41 through M-46 at time of writin, others may be added, and should be equally suitable.
