For purchasing managers in the aerospace and energy industries, the biggest pain point is price volatility. GH4169 is a high-value superalloy whose price is highly dependent on the prices of nickel (Ni) and niobium (Nb).
Pain Points:
London Metal Exchange (LME) Price Volatility: Surges in global market prices can lead to unexpected cost increases of 20-30% overnight.
Middleman Markups: Sourcing from local traders adds multiple layers of profit (up to 25%) and obscures the metallurgical origin of the material.
The Quality and Cost Trap: "Low-price" offers often mean that material melted in a single batch cannot pass high-cycle fatigue testing.
At Gnee Alloy, we eliminate your concerns. As a Tier 1 manufacturer, Gnee Alloy offers LME-linked pricing and direct-from-factory access, ensuring you get the most cost-effective solution.

GH4169 (Inconel 718) 6mm-30mm Bar Price Guide
GH4169 (Inconel 718) 6mm-30mm Bar Price Guide
By mid-2026, the price of GH4169 (Inconel 718) bars with diameters ranging from 6 mm to 30 mm will typically be between $15 and $70 per kilogram, with prices significantly influenced by order volume, surface finish (bright/polished and black), and the price of nickel on the London Metal Exchange (LME).
Are Alloy 718 and Inconel 718 the same?
Inconel 718 (Alloy 718) is a precipitation-hardening nickel-chromium superalloy (UNS N07718). There is no difference between Alloy 718 and Inconel 718-their chemical compositions are exactly the same. "Inconel" is a registered trademark, while "Alloy 718" is a generic name.

3. Price range for GH4169 by quantity (approx.)
Small quantity (sample/trial, < 100 kg): $40-70/kg;
Medium quantity (100-1000 kg): $30-50/kg;
Large quantity (> 1000 kg): $15-30/kg.
4. Factors affecting the price of GH4169 alloy 6mm-30mm bars
Diameter accuracy: Smaller diameter bars (6mm-12mm) require precision cold drawing or centerless grinding, and their production cost is generally higher than that of 20mm-30mm bars.
Surface finish: Bright, polished, or peeled polished bars are more expensive than black, hot-rolled, or rough-forged bars.
Raw material cost: As a nickel-based superalloy (containing more than 50% nickel), its price is directly affected by the London Metal Exchange (LME) nickel price.
ASTM/AMS standards: Materials certified according to ASTM 596 or ASTM B637 are more expensive.

FAQ
Q1: Why does GH4169 price vary so much between solution-treated and fully aged bars?
A: Fully aged material (AMS 5663) requires an additional 16-hour multi-stage heat treatment cycle in a vacuum furnace. This process adds significant energy and labor costs but delivers the elite 1030 MPa yield strength required for high-stress service.
Q2: Can I lock in a price for a 12-month supply contract?
A: Yes. We offer price-hedging strategies for our long-term partners. By locking in a fixed fabrication fee and a floating surcharge based on the LME index, we protect your project from sudden market volatility.
Q3: Is there a surcharge for h9 tolerance precision grinding?
A: Precision centerless grinding is a labor-intensive process that ensures zero-vibration and zero-jam feeding for your CNC machines. While there is a slight premium per kg, it is more Cost-effective as it reduces your tooling wear and scrap rates by 30%.
Q4: What is your Minimum Order Quantity (MOQ) for wholesale pricing?
A: For in-stock standard sizes (6mm-30mm), we support innovation by offering a low MOQ of 50kg for initial wholesale rates, with deeper discounts for orders over 500kg.
