Inconel 600 is a solid-solution nickel-chromium-iron alloy widely used in high-temperature and corrosion-resistant applications. Its price fluctuates based on raw nickel market trends, production method, product form (bar, sheet, pipe, wire), and certification standards. Below is a detailed price breakdown and factors affecting Inconel 600 cost in industrial markets.
Typical Inconel 600 Price Range by Product (USD/kg)
| Product Type | Price Range (Standard) | Remarks |
|---|---|---|
| Round Bar | $8 – $16 | Annealed, ≤100 mm diameter |
| Cold Rolled Sheet | $10 – $18 | Thickness 0.5–3 mm |
| Hot Rolled Plate | $12 – $20 | Thickness ≥4 mm |
| Seamless Pipe | $15 – $26 | Standard ASTM B167 / B829 |
| Welding Wire (ERNiCr-3) | $25 – $32 | Spool packed, 1.2 mm diameter |
Inconel 600 Price Impact Factors
| Factor | Effect |
|---|---|
| Nickel Content (~72%) | Major cost driver; LME nickel price heavily influences alloy cost |
| Form Complexity | Bar and pipe require more shaping and testing than flat sheet |
| Order Quantity | Small quantities (<50 kg) often priced 15–30% higher |
| Certification | NACE, 3.1 MTC, or PED adds $1–3/kg |
| Processing Level | Bright drawn or polished materials priced higher than black or mill finish |
Inconel 600 vs Other Nickel Alloys (Price Comparison)
| Alloy | Composition | Typical Price Range |
|---|---|---|
| Inconel 600 | Ni ~72%, Cr ~15%, Fe ~8% | $8 – $20 |
| Inconel 625 | Ni ~58%, Cr ~21%, Mo ~9% | $15 – $28 |
| Hastelloy C276 | Ni ~57%, Mo ~16%, Cr ~15% | $18 – $35 |
| Monel 400 | Ni ~65%, Cu ~32% | $10 – $18 |
Industrial Usage and Pricing Strategy
1. For heat-treatment tooling: Round bars in Inconel 600 are ideal; polished condition preferred to reduce scaling and oxidation.
2. For exhaust ducts or thermal reactors: Use plate or sheet; cold rolled offers better dimensional control and finish.
3. For critical chemical equipment: Ensure pipe/tube complies with ASTM B167/B829 with ultrasonic testing and pressure test certification.
4. Cost-saving tip: For large volumes (>1 ton), price can be negotiated down by 5–10% with most Asian suppliers.
Related Questions
What is the average price of Inconel 600 per kg?
The typical price of Inconel 600 ranges from $8 to $20 per kg, depending on the product type and surface finish.
Why is Inconel 600 so expensive?
Because it contains high nickel and chromium content, Inconel 600 has superior resistance to heat and corrosion, which makes its raw material and processing cost high.
Is Inconel 600 cheaper than Inconel 625?
Yes, Inconel 600 is generally 20–30% cheaper than Inconel 625 due to lower alloying elements and simpler performance requirements.
