How Expensive Is Inconel?

Inconel is a premium-grade nickel-based alloy known for its exceptional strength, oxidation resistance, and corrosion resistance in extreme environments. It is widely used in aerospace, chemical processing, marine, nuclear, and power generation industries. But with all these high-performance attributes, one question often arises: How expensive is Inconel?

This comprehensive guide explores the cost of Inconel, the factors affecting its price, and how it compares to other industrial metals. Whether you are a procurement engineer, material buyer, or project manager, understanding the cost dynamics of Inconel can help you make informed decisions.

What Is Inconel?

Inconel is a family of austenitic nickel-chromium-based superalloys developed by Special Metals Corporation. The most common grades include:

  • Inconel 600 (UNS N06600)

  • Inconel 625 (UNS N06625)

  • Inconel 718 (UNS N07718)

  • Inconel X-750 (UNS N07750)

These alloys maintain strength and stability in high-temperature and corrosive environments, making them indispensable in jet engines, exhaust systems, chemical plants, and offshore rigs.

How Much Does Inconel Cost?

The cost of Inconel varies significantly depending on the grade, form (bar, pipe, sheet, wire), market demand, and global nickel prices. As a general reference, Inconel can cost between $25 to $70 per kilogram, with high-grade or heat-treated variants going even higher.

Average Price by Grade (Reference Range):

  • Inconel 600: $25 – $35/kg

  • Inconel 625: $30 – $50/kg

  • Inconel 718: $40 – $70/kg

  • Inconel X-750: $35 – $60/kg

Note: Prices fluctuate daily due to global nickel markets, energy costs, and alloy demand. Always request a current quotation.

Factors Affecting Inconel Prices

1. Raw Material Content

Inconel contains a high percentage of nickel (58%–72%), along with chromium, molybdenum, niobium, iron, and trace elements. Nickel itself is a costly raw material. As a result, the more nickel-intensive the alloy, the more expensive the final product.

2. Grade and Alloy Composition

Each Inconel grade has a different composition tailored for specific applications. For example:

  • Inconel 625 is valued for seawater and chemical resistance.

  • Inconel 718 is chosen for its exceptional strength and creep resistance at high temperatures.

Higher alloying content typically means a higher price.

3. Product Form

Inconel is available in various forms such as:

  • Round bars

  • Forged blocks

  • Seamless pipes

  • Plates and sheets

  • Welding wire

Forged and heat-treated items generally cost more due to added manufacturing steps.

4. Heat Treatment and Certification

Materials with AMS, ASTM, or ISO certifications or specific heat treatments (e.g., solution annealing, aging) are more expensive due to the added processing and testing requirements.

5. Supply Chain and Lead Time

Global supply chain issues, geopolitical instability, and transportation costs affect availability and pricing. Lead times for special sizes or custom-made products can stretch pricing as well.

6. Order Quantity

Bulk purchases often qualify for volume discounts. Conversely, custom or small-batch orders typically cost more per unit due to setup and machining overheads.

Inconel vs. Other Industrial Metals: Price Comparison

Material Approx. Price Range (USD/kg) Key Properties
Inconel 625 $30 – $50 High-temp strength, corrosion resistance
Stainless Steel 316 $3 – $5 General corrosion resistance
Titanium Grade 5 $25 – $35 Lightweight, high strength
Hastelloy C-276 $40 – $60 Extreme corrosion resistance
Monel 400 $20 – $35 Sea water resistance, moderate strength

As seen, Inconel is more expensive than stainless steel but competes closely with other superalloys like Hastelloy and Monel in pricing.

When Is Inconel Worth the Price?

Though expensive, Inconel is cost-effective in the long run in the following applications:

  • High-temperature components like turbine blades and heat exchangers.

  • Corrosive chemical processing where stainless steel would fail prematurely.

  • Marine or offshore equipment exposed to salt water and high stress.

  • Aerospace parts where high strength-to-weight ratio and thermal resistance are critical.

Using cheaper materials in these situations can result in higher failure rates, downtime, and replacement costs.

How to Buy Inconel at the Best Price

  1. Work with Trusted Suppliers
    A reliable supplier like sasaalloy provides stable pricing, material traceability, and full certification.

  2. Request Mill Test Reports (MTR)
    This verifies the chemical and mechanical properties of the alloy.

  3. Consider Near-Net Shapes
    Reduce machining waste by ordering bars or sheets in sizes close to final dimensions.

  4. Combine Orders
    Consolidate purchases to qualify for volume pricing.

  5. Keep an Eye on Nickel Markets
    Global nickel prices heavily impact Inconel cost. Timing your purchase can make a difference.

Why Inconel Is a Long-Term Investment

Although the initial cost is high, Inconel’s durability, resistance to corrosion, and mechanical integrity help extend equipment life and reduce maintenance. For mission-critical systems in oil and gas, aerospace, nuclear, or chemical plants, Inconel often proves to be the most cost-effective choice over the lifecycle of the equipment.

Companies like sasaalloy support industries with competitively priced Inconel products and expert guidance in selecting the right alloy for the job.

Final Thoughts

So, how expensive is Inconel? The answer depends on the grade, form, treatment, and market conditions. But across the board, Inconel is considered one of the higher-priced industrial alloys due to its advanced properties and performance under extreme conditions.

Still, when failure is not an option, Inconel stands out as a smart, long-term material investment.

Whether you’re specifying material for a high-performance turbine, offshore pipeline, or chemical reactor, working with the right supplier like sasaalloy can help balance cost and performance with confidence.
