A Comparison Guide to Inconel 600 and 601 Sheets
A Comparison Guide to Inconel 600 and 601 Sheets
Inconel 600 and 601 are both nickel-chromium alloys designed for high-temperature and corrosive environments, but they are engineered for different specialized uses. Inconel 600 is best for general corrosion resistance and heat treatment, while Inconel 601 is specifically engineered for superior oxidation resistance at higher temperatures due to its added aluminum.
Is Inconel 601 sheet metal magnetic?
Inconel 601 sheet metal is a non-magnetic nickel-chromium alloy with properties including high-temperature strength comparable to alloy 18-8 and high resistance to organic and inorganic corrosion. Inconel 601 sheet metal performs well over a temperature range from low temperatures to 2000°F (approximately 1093°C).

Key Comparison Areas for Inconel 600 and Inconel 601 Plate Selection
1. High-Temperature Oxidation Resistance
Due to its higher aluminum content, Inconel 601 plate exhibits superior high-temperature oxidation resistance compared to 600 thin plate. While 600 medium-thick plate maintains good performance below 1093°C, 601 alloy plate is designed for more demanding applications, reaching up to 1204°C, making it particularly suitable for alternating heating and cooling conditions.
2. Corrosion Resistance
Inconel 600 medium-thick plate performs better in aqueous corrosive environments and, due to its higher nickel content, offers superior resistance to reduction and oxidation in medium to high-temperature chemical environments compared to 601 plate.
Inconel 601 alloy plate performs exceptionally well in harsh oxidation and carburizing environments at extremely high temperatures.
3. Mechanical Properties
At room temperature, both have similar strengths. At high temperatures, Inconel 601 alloy plate exhibits superior creep rupture strength. However, Inconel 600 sheet often offers higher toughness in certain structural applications.
Inconel 600 sheet metal core application scenarios:
Chemical and petrochemical equipment (European precision chemicals):
Applications: Reactor linings, distillation towers, fatty acid processing equipment.
Nuclear power industry (French/German nuclear grade standards):
Applications: Nuclear reactor steam generator baffles, control rod conduit components.
Food and electronics industry:
Applications: Vacuum furnace components, electron tube supports, food processing containers.
Inconel 601 sheet metal core application scenarios:
Heat treatment and industrial furnace manufacturing (Italian/German heat treatment giants):
Applications: Carburizing baskets, brazing furnace baffles, muffle furnace linings, heat treatment trays, heating element support frames.
Environmental protection and waste incineration (Polish/Spanish green energy):
Applications: Combustion chambers of waste incinerators, baffles for exhaust gas treatment systems.
Aero-engine parts:
Applications: Jet engine exhaust system components, combustion chamber linings.
How to choose between Inconel 600 and Inconel 601 sheet?
If you require high resistance to acids, salts, or general corrosion, or if the operating temperature is below 1000°C, choose Inconel 600 medium-thick sheet.
If you are manufacturing furnace components that need to be used in high-temperature oxidizing environments (above 1100°C), or require resistance to thermal cycling/stripping, choose Inconel 601 sheet.

FAQ
Q: What is the difference between Inconel 600 and ss310?
A: Inconel 600 is more expensive but offers superior corrosion resistance and high-temperature strength. At the same time, Stainless Steel 310 is a more cost-effective option with excellent high-temperature strength and good corrosion resistance.
Q: What is the difference between Inconel 625 and Inconel 601?
A: Inconel 601 has a melting point of 2467°F (1350°C), while Inconel 625 has a melting point of 2375°F (1310°C). In terms of tensile strength at room temperature, Inconel 601 ranges from 590-930 MPa, while 625 is slightly stronger at 690-895 MPa.
Q: Is Inconel 601 magnetic?
A: Inconel 601 plate is a nonmagnetic nickel-chromium alloy with properties that include high temperature strength comparable to 18-8 alloys and high resistance to organic and inorganic corrosives. Inconel 601 plate performs well in temperatures ranging from cryogenic up to 2000°F.
Q: What is Inconel 601 material?
A: INCONEL nickel-chromium-iron alloy 601 (UNS N06601/W.Nr. 2.4851) is a general-purpose engineering material for applications that require resistance to heat and corrosion. An outstanding characteristic of INCONEL alloy 601 is its resistance to high-temperature oxidation.
Q: What is Inconel 600 used for?
A: ASME SB-444 is the same specification used in Part B (Non-ferrous Metals) of the ASME Boiler and Pressure Vessel Code. Materials manufactured according to ASTM B444 can bear the SB-444 designation if they meet all ASME requirements. This is mandatory for pressure vessels, heat exchangers, and piping with standard stamps in the power generation and process industries.
Q: Can you weld an Inconel 600?
A: Inconel 600 welding wire can be joined using TIG, MIG, or plasma arc welding techniques. However, TIG welding, in particular, is recommended for welding Inconel alloys like Inconel 600. Filler metal for welding Inconel 600 is essential to ensure proper fusion and structural integrity.
