Inconel 600
Inconel 600 is a versatile nickel-chromium alloy designed to resist oxidation and corrosion in extreme conditions. Its composition primarily consists of nickel, with chromium and iron as key components, supplemented by small amounts of elements like carbon, manganese, and silicon to enhance its performance. This combination makes Inconel 600 highly effective in environments where both high temperatures and corrosive agents are present.
Inconel 601
Building on the strengths of Inconel 600, Inconel 601 includes aluminum as an additional alloying element, further improving its resistance to oxidation at elevated temperatures. Like its counterpart, it is composed mainly of nickel, chromium, and iron, but its unique formulation allows it to perform exceptionally well in environments with thermal cycling and exposure to sulfur compounds.
Both Inconel 600 and 601 are renowned for their strength and durability, but they differ in their capabilities. Inconel 600 offers excellent tensile strength and ductility, making it ideal for applications that demand a balance of mechanical integrity and corrosion resistance. In contrast, Inconel 601 surpasses its predecessor with higher tensile strength and improved creep resistance, enabling it to endure greater stress in high-temperature environments.
Both alloys are engineered to resist a wide range of corrosive substances and perform reliably in harsh environments. Inconel 600 excels in resisting oxidation, carburization, and chloride-ion stress corrosion cracking, making it suitable for both reducing and oxidizing conditions. Inconel 601, however, goes a step further with its enhanced oxidation resistance, thanks to its aluminum content. This feature makes it particularly effective in conditions involving cyclic thermal exposure or sulfur-containing atmospheres, where maintaining surface stability is crucial.

Inconel 600 and 601 foil prices depend on factors like raw material costs, market demand, production methods, and the foil’s form and dimensions. These alloys, known for their high-performance applications, often experience price fluctuations due to changes in the global metal market and their specialized properties.
Inconel 600 foils typically cost between $24.75 and $44.00 per kilogram, depending on thickness, treatment, and supplier. Inconel 601 foils are slightly pricier, ranging from $27.50 to $56.00 per kilogram. The higher cost of Inconel 601 is attributed to its enhanced oxidation resistance and ability to withstand thermal cycling, making it more suitable for demanding high-temperature applications.
Prices vary by region, with higher costs in North America and Europe compared to Southeast Asia or the Middle East due to factors like shipping, import duties, and local supply chains.
Nickel, a key component in Inconel 600 and 601, heavily influences prices. Market fluctuations due to supply shortages or increased demand (e.g., aerospace, electric vehicles) impact costs. Chromium and aluminum also affect prices, especially during mining or refining disruptions.
Many suppliers apply surcharges to account for volatility in raw material costs, particularly nickel and chromium. Recent reports indicate that surcharges for Inconel 600 range between $5.61 and $5.89 per unit, while those for Inconel 601 are slightly lower, ranging from $4.95 to $5.19 per unit. These surcharges are typically updated monthly or quarterly, reflecting changes in raw material indices.
Procurement managers can save costs by ordering in bulk, negotiating long-term supplier contracts, and sourcing from regions with lower production costs. Monitoring nickel and chromium market trends to time purchases when prices are lower is also effective.
Inconel 600 is made up of about 75% nickel and 16% chromium, with the rest consisting of iron and small amounts of elements like carbon, manganese, and silicon. This blend gives Inconel 600 excellent resistance to oxidation and corrosion, making it ideal for use in high-temperature and harsh environments.
