Nickel Alloy Grade Data Sheet

HAYNES 230

HAYNES 230 is a nickel-chromium-tungsten-molybdenum solid-solution-strengthened alloy offering an exceptional combination of high-temperature strength, oxidation resistance, thermal stability and fabricability. It is particularly effective for long-term structural service above approximately 650 °C and can resist continuous exposure to air or combustion gases at temperatures up to about 1150 °C. Typical applications include gas-turbine combustion cans, transition ducts, flame holders, furnace retorts, heat-treatment fixtures, high-temperature bellows, thermocouple protection tubes, catalyst-grid supports, recuperator internals, heat exchangers and industrial furnace components.

Material Selection Guide

When to consider HAYNES 230

This guide helps buyers connect service conditions with the typical advantage of Alloy 625. Final selection should consider medium concentration, temperature, pressure, fabrication, availability and budget.

Service Requirement Recommended Alloy Reason for Selection Buyer Note
High creep strength and oxidation resistance above 650 °C HAYNES 230 Provides an effective balance of load-bearing strength, stability and environmental resistance. Use time-temperature-stress data for final component design.
Long-term air or combustion-gas exposure up to 1150 °C HAYNES 230 Offers excellent cyclic and continuous oxidation resistance with good fabricability. Confirm load, atmosphere, thermal cycling and required service life.
Maximum oxidation resistance in relatively low-stress service HAYNES 214 Its alumina-rich scale provides exceptional oxidation resistance above approximately 955 °C. HAYNES 214 generally has lower structural strength at the highest temperatures.
Established cobalt-base gas-turbine combustor alloy HAYNES 188 Provides strong high-temperature performance and extensive aerospace service history. HAYNES 230 may provide improved thermal stability in selected applications.
ASME high-temperature pressure construction HAYNES 230 or Alloy 617 Both have established pressure-code applications and high-temperature strength. Compare the current code coverage, allowable stresses and service environment.
Aqueous chloride or reducing-acid corrosion Select Alloy 625 or a Hastelloy corrosion-resistant grade HAYNES 230 is primarily optimized for high-temperature strength and gaseous environments. Provide the complete process chemistry, concentration and temperature.

FAQ

HAYNES 230 questions from buyers

Find practical answers about procurement, standards, fabrication and industrial applications.

HAYNES 230 is used for gas-turbine combustion cans, transition ducts, flame holders, furnace retorts, heat-treatment fixtures, high-temperature bellows, thermocouple protection tubes, catalyst-grid supports, recuperators and heat exchangers.

Yes. UNS N06230 is the standardized designation for HAYNES 230 base material. HAYNES 230-W matching filler metal is identified separately as UNS N06231.

The alloy can provide continuous oxidation resistance in air or combustion gases up to approximately 1150 °C. Allowable structural or pressure-design temperatures are lower and must be determined from creep data, ASME rules and the applicable Code Cases.

HAYNES 230 is nickel based, while HAYNES 188 is cobalt based. Both provide high-temperature strength and oxidation resistance, but HAYNES 230 generally offers excellent long-term phase stability, lower thermal expansion and broad ASTM and ASME product coverage.

YSN128 can quote plate, sheet, strip, round bar, rod, wire, seamless or welded pipe and tube, forgings, flanges, fittings, fasteners and HAYNES 230-W matching welding wire.

Common standards include ASTM B435 and AMS 5878 for plate and sheet, ASTM B572 and AMS 5891 for bar, ASTM B622 for seamless tube, ASTM B619 or B626 for welded tubular products, ASTM B564 for forgings and ASTM B366 for fittings.

Yes. HAYNES 230 can be welded by GTAW, GMAW, SMAW and resistance-welding methods. ERNiCrWMo-1 HAYNES 230-W filler is recommended, preheating is normally unnecessary, and interpass temperature should generally remain below 93 °C.

Please send the UNS or alloy grade, product form, dimensions, quantity, ASTM, ASME or AMS specification, delivery condition, operating temperature, design pressure or load, inspection requirements, certificate type and destination.
