Selection Recommendations for Aerospace Applications
In the context of aircraft engines and gas turbines, the Incoloy 800 series is typically not employed for the hottest rotating turbine blades—a domain traditionally reserved for alloys such as Inconel 718 or Waspaloy. However, thanks to its excellent resistance to high-temperature oxidation and moderate creep strength, it remains a proven and established choice for static high-temperature components.
- Incoloy 800: Suitable for operating conditions below 650°C, such as engine nacelle heat shields. Note, however, that its creep resistance is limited.
- Incoloy 800H (UNS N08810): This is the predominant grade for aircraft engine casings and ring components. The coarse-grain structure—achieved through a solution annealing treatment at 1100°C—imparts superior rupture strength at temperatures exceeding 650°C.
- Incoloy 800HT (UNS N08811): A higher combined content of Aluminum and Titanium (≥0.85%) results in enhanced creep resistance. If your components are required to operate for extended periods within the 700°C range, or must withstand frequent thermal cycling, Incoloy 800HT represents a more robust and reliable choice.
How Lork Group Serves Aviation Clients
1. Every Heat Has an"ID Card"
In aerospace procurement, the greatest concern is an unclear material origin. For every batch of Incoloy 800 series bars we supply, we provide the original Mill Test Certificate (MTC) from the raw material manufacturer. Furthermore, upon request, we can directly mark aerospace-specific identifiers—such as heat number, alloy grade, and dimensions—onto the material surface using laser engraving or electro-etching.
2. Comprehensive Testing Compliant with AMS 5766
We offer more than just chemical composition analysis and room-temperature tensile data. For our aerospace clients, we can coordinate the following specialized tests:
High-temperature tensile testing (at specified temperature points, e.g., 700°C)
Grain size evaluation (to ensure Incoloy 800H/800HT meets specific fine-grain or coarse-grain requirements)
Ultrasonic Testing (UT) or Eddy Current Testing (ET)
3. Rapid Response for Small-Batch, High-Variety Orders
Aerospace R&D and spare parts projects often involve low-volume requirements but demand urgent delivery timelines. We accept minimum orders starting from 100 kg, and common stock sizes (diameters ranging from 10 mm to 200 mm) can be shipped within 7–10 business days. For special alloy variants requiring vacuum melting, we can also arrange for customized small-batch furnace production.
Why Lork Group Is Worth a Trial for Aviation Clients
We are not merely traders who simply consult product manuals. Lork Group’s sales engineers possess an in-depth understanding of the casting, forging, and machining characteristics of high-temperature alloys. When you specify requirements—such as"no deformation after machining"or"a specific grain size"—we provide precise technical responses rather than vague assurances like"that should be possible."You are welcome to request samples for small-batch trials to verify our commitments using actual performance data.
