Shaanxi Shangyou Stainless Steel Co., Ltd. supplies Nickel Alloy 601, also known as Inconel 601, identified as UNS N06601 and Werkstoff 2.4851, in plate, sheet, strip, round bar, rod, seamless and welded tubing, pipe, and forging forms. Our Alloy 601 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; and ASTM B564 / ASME SB-564 for forgings.
Nickel Alloy 601 is a nickel-chromium-iron alloy with an addition of aluminum, specifically developed for outstanding resistance to high-temperature oxidation, even under cyclical heating and cooling conditions. The nickel base (58-63%) combined with substantial chromium content (21-25%) provides resistance to many corrosive media and high-temperature environments, while the aluminum addition (1.0-1.7%) further enhances oxidation resistance. Alloy 601 also has good resistance to aqueous corrosion, high mechanical strength, and is readily formed, machined, and welded. The alloy is not age-hardenable and is hardened and strengthened through cold work only.

Annealed
Alloy 601 is normally supplied in the annealed condition. The standard annealing treatment is performed at approximately 1,975°F – 2,100°F (1,079°C – 1,150°C) followed by rapid cooling. This treatment provides optimal corrosion resistance and ductility for forming and fabrication.
Cold Working / Spring Temper
Alloy 601 is not age-hardenable – strength increases only through cold working. Annealed material typically exhibits tensile strength of 80 – 115 ksi (550 – 790 MPa), while spring temper can achieve 180 – 210 ksi (1,240 – 1,448 MPa).
Alloy 601 provides outstanding resistance to high-temperature oxidation, carburization, and sulfidation, with good aqueous corrosion resistance.
Key Corrosion Characteristics:
- Outstanding oxidation resistance up to 1,200°C (2,200°F), even under cyclical heating and cooling.
- Good resistance to carburization and sulfidation at elevated temperatures.
- Good aqueous corrosion resistance to many acid and aqueous salt solutions.
- Resistance to chloride stress-corrosion cracking due to high nickel content.
- Non-magnetic in all conditions.
- Retains mechanical strength at elevated temperatures.
Selection Considerations:
- For applications requiring superior oxidation resistance above 1,000°C, Alloy 601 was specifically developed to outperform Alloy 600.
- Excellent for thermal cycling applications due to spalling resistance.
- Good weldability – welding should be performed using qualified procedures.
- Final selection must consider the specific medium, temperature, and exposure conditions.
- Thermal Processing: Industrial furnace components, radiant tubes, muffles, retorts, baskets, trays, fixtures for annealing, carburizing, carbonitriding, nitriding operations; strand-annealing tubes, woven-wire conveyor belts, chain curtains, burner nozzles.
- Chemical Processing: Process heaters, condenser tubes in sour-water strippers, insulating cans in ammonia reformers, catalyst regenerators, air preheaters.
- Aerospace: Jet-engine igniters, combustion-can liners, diffuser assemblies, containment rings in gas turbines.
- Power Generation: Superheater tube supports, grid barriers, ash-handling systems.
- Pollution Control: Thermal reactors in exhaust systems, combustion chambers in solid-waste incinerators.
