Physical Properties of 2.4665 (NiCr21Fe18Mo9) — Density, Thermal Expansion, Conductivity & Elastic Modulus

Physical properties are engineering constants that control how a forged part performs in use — they affect thermal fatigue life, interference fit sizes, and structural bending under load. For 2.4665 NiCr21Fe18Mo9, these values change with temperature: they differ greatly between room temperature and operating temperature. That is why our engineering team always provides data at different temperatures instead of single fixed values. The table below shows standard reference values for UNS N06002 in the solution annealed (+AT) condition, compiled from industry technical documents and ASM material handbooks.

Temperature-Dependent Physical Properties of 2.4665 NiCr21Fe18Mo9

The following data is essential for thermal stress analysis, interference fit calculations at operating temperature, and creep-fatigue design. Values shown reflect the annealed (+AT) material condition used in our standard forging deliveries.

Manufacturer's Note on Thermal Expansion in Forged Components: When designing shrink-fit assemblies or calculating bore sizes for turbine disc forgings at operating temperature, keep in mind that the average thermal expansion coefficient at 760°C (16.2 μm/m·K) is about 22% higher than its room-temperature value. Procurement teams using only single-value data sheets often overlook this difference. Our applications engineering team offers free thermal expansion calculation support for intricate assemblies upon request.

2.4665 NiCr21Fe18Mo9 vs. Other High-Temperature Nickel Alloys: Manufacturer's Material Selection Guide

In over 25 years of producing forgings from different nickel alloy grades, our engineering team has seen a consistent pattern: engineers usually shortlist 2.4665 along with three to five other alloys before making a final choice. The decision is rarely simple — each alloy performs best within its own range, and the wrong pick either wastes costs or causes parts to fail early. The comparison below comes from real production and usage experience, not just standard data sheets. We produce all five alloys discussed here, so we have no business reason to recommend one over another.

When to Choose 2.4665 NiCr21Fe18Mo9 Over Alternatives — Decision Framework

Based on our project experience with aerospace, power generation, and petrochemical customers, 2.4665 is clearly the best choice when all three of the following conditions apply at the same time: (1) operating temperature ranges from 900°C to 1150°C under repeated or constant high heat; (2) the working environment is oxidizing or mixed (air, flue gas, combustion gases); and (3) the part needs to be forged to control grain structure, instead of being cast or made from wrought plate. If your operating temperature is mostly below 800°C, and the main issue is water-based corrosion rather than high-temperature oxidation, Inconel 625 (2.4856) or Hastelloy C-276 (2.4819) will usually give longer service life for the cost than 2.4665.

Corrosion & Oxidation Resistance of 2.4665 NiCr21Fe18Mo9 — Mechanisms, Performance Data & Environmental Limits

The corrosion and oxidation resistance of 2.4665 NiCr21Fe18Mo9 is not just one single feature — it comes from three separate protective effects, each activated by a different element in the alloy. Knowing which mechanism protects against which environment will help you decide if 2.4665 is the right material for your use. Our technical team has summarized the following based on direct metallurgical tests of returned parts, plus reference data and real production experience.

Mechanism 1 — High-Temperature Oxidation Resistance (Chromium-Driven)

At temperatures above 600°C in oxidizing environments (air, oxygen, flue gas), 2.4665 mainly uses its chromium content (20.5–23.0 wt%) to form a continuous, tightly bonded Cr₂O₃ (chromia) layer on the part surface. This layer can repair itself during repeated temperature changes: if the oxide layer cracks from heat shock, new chromium moves from inside the alloy to cover the exposed metal again. Laboratory cyclic oxidation tests at 1090°C (1000 hours of steady and cycling heat) show a weight gain of less than 2 mg/cm² for 2.4665 — much lower than 310S stainless steel at the same temperature. This makes 2.4665 ideal for parts with frequent heat cycling, such as jet engine afterburner sections and industrial annealing furnace doors.

Mechanism 2 — Reducing Atmosphere and Sulfidation Resistance (Molybdenum-Driven)

The high molybdenum content (8.0–10.0 wt%) in 2.4665 gives it corrosion resistance in chemically reducing environments, especially in hydrogen-containing atmospheres, partially burned fuel gas, and petrochemical process flows with H₂S. Molybdenum increases the alloy’s critical passivation potential, reduces hydrogen formation on the metal surface, and helps prevent the passive layer from failing in moderately reducing acid conditions. In industrial furnace settings that are sometimes exposed to reducing burner atmospheres, 2.4665 furnace rolls keep their oxide layer intact longer than NiCr-only alloys (such as 2.4851 NiCr23Fe), because molybdenum slows down the loss of chromium at the metal-scale boundary. However, it is important to note that for strong reducing acid use (concentrated HCl, HF) at room temperature, Hastelloy C-276 (2.4819) performs much better due to its higher molybdenum content. 2.4665 is not designed for water-based reducing acid service below 300°C.

Mechanism 3 — Hot Corrosion Resistance (Nickel + Iron Matrix Stability)

In combustion environments where sodium sulfate (Na₂SO₄) deposits form on part surfaces — a failure mode known as Type I Hot Corrosion, occurring between 750°C and 950°C — the high Nickel content (balance, typically 45–50 wt%) and Iron (17–20 wt%) of 2.4665 provide resistance to catastrophic sulfidation attack. The alloy is rated as resistant to Type I Hot Corrosion in gas turbine combustor environments up to approximately 900°C, making it widely used for combustion hardware in industrial gas turbines. For Type II Hot Corrosion (low-temperature sulfate attack, 600°C–750°C), 2.4665 performance is acceptable but not outstanding — alloys with higher Cr content such as Inconel 617 offer better resistance in this specific sub-range.

Oxidation Performance Reference: Cyclic Weight Change at 1090°C vs Common Alloys

Note: Values below are indicative reference data compiled from published industry technical literature and standard material handbooks. They represent typical performance ranges, not guaranteed specifications. Actual performance may vary depending on specific atmosphere composition, thermal cycle parameters, and material heat.

Limits of Corrosion Resistance — Critical Engineering Warning: 2.4665 NiCr21Fe18Mo9 is not recommended for long-term use in high-concentration chloride solutions at high temperatures (above 150°C), strongly alkaline environments (pH > 13) with halide contamination, or molten salt environments containing alkali halides. In these conditions, other alloys with higher nickel and molybdenum contents such as 2.4819 (C-276) or 2.4605 (C-2000) are more suitable. If your application involves any of these conditions, please consult our technical team before selecting 2.4665 forgings.

Welding, Machining & Fabrication of 2.4665 NiCr21Fe18Mo9 Forging Parts — Practical Guide from the Forge

One common misunderstanding about 2.4665 NiCr21Fe18Mo9 is how easy it is to fabricate. Engineers who only know this material for its high-temperature performance often think it is hard to weld and machine. In fact, 2.4665 is one of the easier nickel alloys to work with, as long as a few main rules are strictly followed. The advice below comes directly from our worldwide customers’ fabrication shops and our own in-house experience machining and welding 2.4665 parts.

Welding of 2.4665 NiCr21Fe18Mo9

Weldability Rating: Good — 2.4665 can be welded using all common fusion welding methods, including GTAW/TIG, GMAW/MIG, PAW, and SMAW. At normal workshop temperatures above 15°C, the alloy does not need preheating before welding. This makes production much simpler compared to some nickel alloys that easily develop strain-age cracking.

Recommended Filler Metals for 2.4665 Welding

• Primary Filler (TIG / MIG): The standard matching filler for Alloy X / 2.4665 / UNS N06002 is ERNiCrMo-2 (AWS A5.14 / ASME SFA-5.14). It is used with both TIG and MIG welding. Has the same chemistry, oxidation resistance, and weld metal strength as the base material.
• Alternative Filler (higher Mo): ERNiCrMo-3 (Inconel 625 filler) — acceptable for over-alloyed welds where extra corrosion resistance is needed; results in weld metal with slightly lower ductility than ERNiCrMo-2 at elevated temperature.
• SMAW Electrode: ENiCrMo-2 covered electrode for positional welding where TIG is not practical.

Critical Pre-Weld Cleaning Requirements

The most common cause of weld cracking and porosity in 2.4665 parts is surface contamination — especially sulfur, phosphorus, and low‑melting metals such as lead, zinc, and copper. These elements lower the grain-boundary melting point and cause hot cracking in the heat-affected zone. Before welding any 2.4665 forging parts, the following cleaning steps must be strictly followed:

• Degrease the weld zone with acetone or an approved non-halogenated solvent. Chlorinated solvents (trichloroethylene) must not be used — residual chlorine attacks the weld at temperature.
• Remove all marking inks, paint, lubricants, and forming compounds within a minimum of 50mm either side of the intended weld line.
• Do not use zinc-coated (galvanized) fixtures or copper backing bars in contact with the weld zone.
• Use dedicated stainless steel wire brushes for surface preparation — never carbon steel brushes that leave iron contamination.

Post-Weld Heat Treatment (PWHT) Requirements

For most structural fabrications using 2.4665, post-weld heat treatment is not mandatory if the base material was supplied in solution annealed (+AT) condition and the welding procedure was correctly executed with low heat input. However, in the following circumstances, a full solution anneal at 1175°C ± 15°C with rapid quench (water or forced air) is recommended after welding:

• Parts intended for nuclear service, where full material property restoration and residual stress relief are required by code
• Heavy cross-section welds (weld prep depth exceeding 50mm) where multi-pass welding has introduced significant residual stress
• Parts that will experience sustained loading in the 650°C–900°C range, where sensitization in the HAZ could promote intergranular attack

Machining of 2.4665 NiCr21Fe18Mo9 Forging Parts

2.4665 work-hardens at a medium rate — faster than austenitic stainless steels but slower than Inconel 718. The most important rule in machining is to keep the cutting tool engaged with new, unhardened material at all times. Pausing or rubbing a stationary tool against the surface creates a hardened layer that shortens tool life sharply. Our in-house CNC machining team uses the guidelines below, which we can share with your machining staff upon request:

• Tooling: Carbide inserts (ISO P25 or M25 grade for roughing; ISO M10/M15 for finishing) or ceramic inserts for high-speed finishing passes. High-speed steel (HSS) tooling is not recommended for 2.4665 except for very small diameter drilling operations.
• Cutting Speed: 20–45 m/min for roughing with carbide; up to 100 m/min for finishing with sharp carbide inserts. Reduce speed by 20% for interrupted cuts.
• Feed Rate: Keep feed rates positive and consistent — 0.15–0.40 mm/rev for turning. Avoid light intermittent cuts that graze the surface without removing material.
• Coolant: Flood coolant (water-soluble oil, concentration 8–12%) is mandatory. Dry machining causes rapid work hardening and built-up edge on the tool. Ensure coolant reaches the cutting zone directly, not just the chip stream.
• Depth of Cut:  Always cut deeper than the layer hardened by the previous cut. To get through the work‑hardened surface, finishing passes should be at least 0.5mm deep.
• Drilling: Use short-series carbide drills with through-tool coolant where possible. Peck drilling (10–15% of drill diameter per peck) prevents chip packing in deep holes. Reduce feed rate by 30% compared to turning recommendations.

Cold Working & Forming Considerations

2.4665 can be cold formed, such as roll forming, press forming and ring rolling, but it work-hardens much faster than carbon steel. Its yield strength can rise by 30–50% after moderate cold deformation.For formed parts that need later machining or tight dimensional accuracy, intermediate solution annealing at 1175°C with rapid quenching may be needed after heavy cold working over 15% area reduction. This restores ductility and dimensional stability before final machining.In our ring rolling process for 2.4665 seamless rings, we apply intermediate reheating for parts with over 40% total reduction. This guarantees consistent grain matrix and mechanical properties around the full ring circumference.
