For materials scientists and aerospace engineers at Russia's top research centers, a major pain point in materials validation lies in material procurement. Most Tier 1 high-temperature alloy manufacturers refuse small-batch supply, forcing laboratories to purchase entire sheets of material for a limited number of test samples.
Furthermore, laboratory testing demands absolute structural integrity and precise dimensions. Even a tiny defect or an unverified heat number can ruin months of high-temperature fatigue or tensile testing.
At Gnee Steel, we are dedicated to bridging this gap. We offer GH4169 sheet samples specifically designed for materials validation, with low minimum order quantities to support your innovative and groundbreaking R&D projects.

GH4169 Certified Sheet Material Sample and Size Supply Guide
GH4169 Certified Sheet Material Sample and Size Supply Guide
GH4169 (also known as Inconel 718 or UNS N07718) is a precipitation-strengthened nickel-based superalloy sheet with excellent strength and corrosion resistance, and an operating temperature range of -253°C to 650°C. It is widely used in aerospace, gas turbine, and nuclear industries.
Is GH4169 difficult to machine?
This nickel-based superalloy is a common material in the aerospace industry, possessing excellent strength and heat resistance-but these very properties make it extremely difficult to machine. GH4169 is prone to rapid work hardening, generating extremely high temperatures at the tool-workpiece interface, thus accelerating tool wear.
1. Certified GH4169 Sheet Specifications (AMS/ASTM)
Standards: Certified GH4169 sheets are typically supplied according to SAE AMS 5596 (sheets, strips, and plates) or ASTM B670 standards.
Conditions: Supplied in annealed or solution-treated condition, with precipitation hardening (aging) possible for high mechanical properties.
Documents: Certified materials include an EN 10204 3.1B manufacturer's test certificate, chemical composition report, and mechanical property report.
2. GH4169 sheet samples were custom-made according to ASTM and GOST standards.
We employ advanced custom processing technology to ensure that your test samples are ready for immediate use in the testing machine upon arrival.
| Specimen Type | Common Dimensions (mm) | Processing Method | Typical Test |
| Tensile Coupons | 0.8mm - 3.0mm Thickness | Wire EDM / Precision Sawing | ASTM E8 / E21 Tensile |
| Fatigue Blanks | Custom shapes per drawing | CNC Machining / Grinding | High-Cycle Fatigue (HCF) |
| Creep Specimens | Forged blocks or thick plate | Precision Lathe / Sawing | Stress-Rupture Testing |
| Metallographic | 10x10 / 20x20 Coupons | Cold Cutting / Polished | Grain Size & Phase Analysis |
Advanced Surface Finishes: We offer Precision Ground finishes (Ra ≤ 0.4μm) to eliminate surface stress initiators, ensuring the most accurate data for your Material Life Cycle simulations.

3. GH4169 Available Sheet Sizes and Specifications
GH4169 sheet is available in a variety of sizes and specifications, with precision thicknesses customizable to meet aerospace application requirements.
Thickness: From thin strip (< 0.1 mm) to thick sheet (> 5 mm), typically up to 1 inch (25.4 mm), conforming to AMS 5596 standards.
Width: Standard widths are typically 0.5 meters to 1 meter (approximately 20 inches to 40 inches), with rolls available in custom widths up to 650 mm.
Length: Custom lengths are available, typically tailored to specific processing requirements.
Tolerances: High precision; tolerances are typically more stringent for cold-rolled sheet and strip.

FAQ
Q1: What is the Minimum Order Quantity (MOQ) for GH4169 test specimens?
A: We support R&D by offering MOQs as low as 1-5 pieces for standard sheet coupons or small forged blocks, depending on the required dimensions.
Q2: Can you provide specimens in the "Solution Treated" or "Fully Aged" state?
A: Yes. We can supply specimens in the Solution Treated condition (easier for you to finish-machine) or Fully Aged (solution + double aging) per AMS 5596, ready for immediate mechanical testing.
Q3: Do you offer wire-cutting (EDM) for complex specimen geometries?
A: Absolutely. Our Custom Fabrication center utilizes precision Wire EDM to provide complex "dog-bone" or "CT" (Compact Tension) specimens based on your technical drawings.
Q4: Is GH4169 interchangeable with Russian KhN-series alloys for testing?
A: GH4169 is the technical equivalent of Inconel 718. While it serves as a replacement for many high-nickel Russian grades in international projects, we provide full chemical data so your metallurgists can confirm compatibility for your specific experiment.
