Product Description

Inconel 600 (UNS N06600, W.Nr. 2.4816, Alloy 600) is a standard engineering material that has proven itself across industries for over half a century. This nickel-chromium alloy delivers an exceptional combination of high temperature strength (up to 2000°F / 1093°C), excellent corrosion resistance, and superior workability.

Unlike many high-performance alloys, Inconel 600 is not precipitation hardenable – it is strengthened only by cold work. This characteristic, combined with its stable austenitic structure, makes it highly fabricable and resistant to chloride-ion stress-corrosion cracking. From cryogenic tanks to furnace components, from chemical reactors to nuclear reactor cores, Alloy 600 remains the trusted choice for applications demanding reliability across a wide temperature range

Typical Applications:
Industry Applications
Chemical Processing Heaters, stills, bubble towers, condensers (fatty acids); evaporator tubes & tube sheets (sodium sulfide); equipment for abietic acid (paper pulp)
Heat Treating Retorts, muffles, roller hearths, furnace baskets, trays, and other furnace components
Aerospace Lock wire, exhaust liners, turbine seals, engine & airframe components
Electronics Cathode-ray tube spiders, thyratron grids, tube support members, springs
Nuclear Reactor core components (Alloy 600T), high-purity water systems
General Industrial Cryogenic tankage, thermocouple sheaths, heat exchangers
Chemical Composition

The unique properties of Inconel 600 derive from its high nickel content (72% minimum) combined with chromium. This balance provides resistance to both reducing (nickel) and oxidizing (chromium) environments.

Element Content (%) Role
Nickel (Ni) 72.0 min Base element – provides resistance to reducing conditions, alkaline solutions, and chloride-ion SCC
Chromium (Cr) 14.0 – 17.0 Provides resistance to oxidizing conditions, sulfur compounds, and high-temperature oxidation
Iron (Fe) 6.0 – 10.0 Adds structural stability and cost-effectiveness
Carbon (C) 0.15 max Controlled for carbide formation at elevated temperatures
Manganese (Mn) 1.0 max Deoxidizer and grain refiner
Silicon (Si) 0.50 max Enhances oxidation resistance
Copper (Cu) 0.50 max Trace element – controlled for corrosion resistance
Sulfur (S) 0.015 max Controlled for hot workability

*For nuclear applications (Alloy 600T), tighter controls on cobalt, boron, and other trace elements are applied – contact us for nuclear-grade certification.*

Typical Mechanical Properties (Annealed Condition)

Inconel 600 is supplied in the annealed condition (solution treated) for optimal corrosion resistance and fabricability. Cold-worked tempers (¼ hard, ½ hard, full hard) are available for wire and strip applications requiring higher strength.

Product Form Condition Tensile Strength (KSI / MPa) Yield Strength 0.2% Offset (KSI / MPa) Elongation (%) Hardness
Rod & Bar Annealed 80 – 100 (550 – 690) 25 – 50 (170 – 345) 55 – 35 65 – 85 HRB
Plate (Hot Rolled) Annealed 80 – 100 (550 – 725) 30 – 50 (205 – 345) 55 – 35 65 – 85 HRB
Sheet (Cold Rolled) Annealed 80 – 100 (550 – 690) 30 – 45 (205 – 310) 55 – 35 88 HRB max
Tube & Pipe Cold Drawn / Annealed 80 – 100 (550 – 690) 25 – 50 (170 – 345) 55 – 35 88 HRB max
Wire (Soft) Annealed 80 – 120 (550 – 830) 35 – 75 (240 – 520) 45 – 20 –
Wire (¼ to ½ Hard) Cold Drawn (No. 1 Temper) 105 – 135 (725 – 930) 70 – 105 (480 – 725) 35 – 15 –
Wire (Spring Temper) Full Hard 170 – 220 (1170 – 1520) 150 – 210 (1035 – 1450) 5 – 2 –

Key Performance Notes:

  • At 1000°F (538°C): Retains approximately 60% of room temperature yield strength.

  • At 1500°F (816°C): Useful strength for non-load-bearing applications; oxidation resistance remains excellent.

  • Cryogenic Performance: Excellent ductility and toughness down to -423°F (-253°C) – no ductile-to-brittle transition.

  • Stress-Relaxation: Low relaxation rate at elevated temperatures makes it suitable for spring applications (high-temperature springs).

Corrosion Resistance: Why Inconel 600 Excels

The nickel-chromium balance in Alloy 600 provides a unique combination of corrosion resistance unmatched by stainless steels or lower-nickel alloys.

Environment Performance Mechanism
Chloride-Ion Stress-Corrosion Cracking (SCC) Virtually immune High nickel content (>72%) prevents SCC common in 300-series stainless steels
Reducing Acids (e.g., dilute HCl, H₂SO₄) Good to excellent Nickel provides resistance in non-oxidizing conditions
Oxidizing Acids (e.g., nitric acid, chromic acid) Good (when properly passivated) Chromium content provides passive film formation
Alkaline Solutions (e.g., caustic soda, NaOH) Excellent Industry standard for caustic evaporators and concentrators
Organic Compounds (fatty acids, abietic acid) Excellent Resists corrosion in organic acid service (paper pulp, fatty acid processing)
High-Temperature Oxidation Excellent to 2000°F (1093°C) Protective Cr₂O₃ scale forms; resists spalling
Sulfur Compounds (at high temperature) Good – better than pure nickel Chromium provides resistance to sulfidation
High-Purity Water (nuclear reactor water) Excellent Proven performance in pressurized water reactor (PWR) systems

Limitations: Alloy 600 is not recommended for strongly oxidizing mineral acids (e.g., concentrated nitric acid) without proper passivation, nor for molten metals or halide salts at very high temperatures.

Frequently Asked Questions (FAQ)

Q: What is the maximum continuous service temperature for Inconel 600?
A: For oxidation resistance: 2000°F (1093°C). For load-bearing applications: consult design codes, but typically up to 1500°F (816°C) for sustained stress. For intermittent service, higher excursions are possible.

Q: How does Inconel 600 compare to Inconel 625 or 718?
A: Inconel 600 is the "workhorse" – excellent high-temperature oxidation resistance, good corrosion resistance, easy to fabricate, but lower strength than 625 or 718. Inconel 625 offers higher strength and better pitting resistance (Mo content). Inconel 718 is precipitation-hardened for maximum high-temperature strength (aerospace rotating parts). Choose 600 for general high-temperature service, chemical processing, and nuclear applications where extreme strength is not required.

Q: Is Inconel 600 magnetic?
A: No. Alloy 600 is non-magnetic in the annealed condition. Cold working may induce slight magnetic permeability, but it remains essentially non-magnetic.

Q: What is Alloy 600T?
A: Alloy 600T is a special nuclear-grade version of Inconel 600 with tighter controls on cobalt, boron, and other trace elements to minimize radiation-induced embrittlement and activation. It is produced under strict quality assurance programs per ASME Section III. Contact us for nuclear-grade certification.

Q: Can Inconel 600 be used in sour gas (H₂S) service per NACE MR-01-75?
A: Yes, in many cases. However, Alloy 600 is not the first choice for sour service – Alloy 625 or Alloy 718 are more commonly specified. Contact our engineers for specific NACE MR-01-75 compliance guidance based on your H₂S partial pressure and temperature.

Q: Do you provide third-party inspection?
A: Yes. We can arrange SGS, TÜV, BV, Lloyds, or Bureau Veritas inspection at the buyer's cost, including witness testing (tensile, hardness, PMI), dimension checks, and positive material identification (PMI).
