Nickel Alloy 600 | UNS N06600 | 2.4816 | Inconel 600

Shaanxi Shangyou Stainless Steel Co., Ltd. supplies Nickel Alloy 600, also known as Inconel 600, identified as UNS N06600 and Werkstoff 2.4816, in plate, sheet, strip, round bar, rod, seamless and welded tubing, pipe, and forging forms. Our Alloy 600 products can be supplied according to ASTM B168 / ASME SB-168 for plate, sheet and strip; ASTM B166 / ASME SB-166 for bar and wire; ASTM B167 / ASME SB-167 for seamless pipe and tube; ASTM B517 / ASME SB-517 for welded pipe; and ASTM B564 / ASME SB-564 for forgings.

Nickel Alloy 600 is a nickel-chromium-iron alloy designed for use from cryogenic to elevated temperatures up to 1093°C (2000°F) with good oxidation resistance and resistance to carburizing and chloride-containing environments. The high nickel content (72% minimum) provides excellent resistance to chloride-ion stress-corrosion cracking and corrosion by alkaline solutions, while the chromium content (14-17%) gives resistance to sulfur compounds and various oxidizing environments. Alloy 600 is non-magnetic, readily weldable, and exhibits cold forming characteristics similar to chromium-nickel stainless steels.

Solution Annealed

Alloy 600 is normally supplied in the annealed condition. The standard annealing treatment is performed at approximately 1,925°F – 1,975°F (1,052°C – 1,079°C) followed by rapid cooling. This treatment provides optimal corrosion resistance and ductility for forming and fabrication.

Cold Working / Spring Temper

Alloy 600 is not age-hardenable – strength increases only through cold working. Annealed material typically exhibits tensile strength of 80 – 110 ksi (552 – 758 MPa), while spring temper can achieve 160 – 200 ksi (1,103 – 1,379 MPa). Cold working should be performed in the solution-annealed condition and may affect the alloy's corrosion resistance in certain environments.

Alloy 600 provides excellent resistance to a wide range of corrosive environments due to its high nickel content and chromium additions.

Key Corrosion Characteristics:

• Virtually immune to chloride stress-corrosion cracking due to high nickel content (72% min).
• Good resistance to oxidation up to 1,093°C (2,000°F), with resistance to carburization and nitriding.
• Excellent resistance to high-temperature corrosion in dry chlorine and hydrogen chloride.
• Resistance to caustic alkalis (particularly with sulfur compounds present).
• Good resistance to alkaline solutions and neutral/alkaline salt solutions.
• Resistance to steam and mixtures of steam, air, and carbon dioxide.
• Good resistance to nitric and sulfuric acids, though poor resistance in hot concentrated nitric acid.

Selection Considerations:

• Not immune to pitting or crevice corrosion in all chloride-containing environments – selection must consider concentration, temperature, and exposure conditions.
• For higher oxidation resistance above 1,000°C, Alloy 601 may be preferred.
• In strong oxidizing solutions like hot concentrated nitric acid, Alloy 600 has limited resistance.
• Final selection must consider the specific medium, temperature, concentration, and oxidizing or reducing conditions.

• Chemical Processing: Reactor vessels, heat exchanger tubes, components for chlorinated and fluorinated hydrocarbons, phenol condensers, soap manufacture, vegetable and fatty acid vessels.
• Heat Treating: Furnace casing seals, fans, and fittings; transport rollers, nozzles; thermocouple protection tubes.
• Nuclear: Control rod ducts, reactor vessels and seals, steam dryers and separators.
• Petrochemical: Tubes for pyrolysis-dichloroethylene, resistant to carburization, chlorine, hydrogen chloride and oxidation.
• Caustic Processing: Production of caustic alkalis, particularly with sulfur compounds present.

Nickel Alloy 600 (UNS N06600), also known as Inconel 600, is a nickel-chromium-iron alloy with good oxidation resistance up to 1,093°C, immunity to chloride stress-corrosion cracking, and good mechanical properties from cryogenic to elevated temperatures.

The UNS designation is N06600; the European Werkstoff number is 2.4816; the EN material symbol is NiCr15Fe.

ASTM B168 / ASME SB-168 applies to plate, sheet and strip; ASTM B166 / ASME SB-166 applies to bar, rod and wire.

ASTM B167 / ASME SB-167 for seamless pipe and tube; ASTM B517 / ASME SB-517 for welded pipe.

No. Alloy 600 is not age-hardenable. Strength increases only through cold working. Annealed tensile strength is 80 – 110 ksi, while spring temper can reach 160 – 200 ksi.

It resists chloride stress-corrosion cracking, oxidation up to 1,093°C, dry chlorine and hydrogen chloride at high temperatures, carburization, nitriding, caustic alkalis, and many alkaline solutions.

Yes. Due to its high nickel content (72% min), Alloy 600 is virtually immune to chloride-ion stress-corrosion cracking.

Alloy 601 was specifically developed to provide higher oxidation resistance than Alloy 600 at elevated temperatures. For applications above 1,000°C with severe oxidation conditions, Alloy 601 is often preferred.

Yes. Alloy 600 exhibits good weldability and resistance to post-weld cracking. Welding should be performed in the solution-annealed condition using qualified welding procedures.

Please provide the standard, product form, dimensions, quantity, heat-treatment condition, inspection requirements, application, working temperature and destination port. For corrosive environments, also specify the chemical medium and concentration.
