INCOLOY 800 Sheet / Plate
Nickel-Iron-Chromium Alloy for High-Temperature and Corrosive Environments
INCOLOY 800 is a nickel-iron-chromium alloy designed for applications requiring excellent resistance to oxidation, carburization, and general corrosion at elevated temperatures. With a controlled nickel content and balanced chromium addition, INCOLOY 800 sheet and plate are widely used in heat-intensive and chemically aggressive environments where structural stability and long-term reliability are critical.
As a professional Chinese nickel-based alloy manufacturer, we supply INCOLOY 800 sheets with stable chemistry, consistent mechanical properties, and flexible dimensional customization for global industrial users.
Typical supply range (custom sizes and tolerances available upon request):
Item | Range / Options | Notes |
Thickness | 0.5 – 50 mm | Sheet typically ≤ 6 mm; Plate typically ≥ 6 mm (project-defined). |
Width | Up to 2000 mm | Slitting service available; define tolerance if critical. |
Length | Up to 6000 mm | Cut-to-length (shearing), waterjet/plasma by agreement. |
Surface finish | 2B / No.1 / BA / Polished | PVC protective film optional for surface-critical parts. |
Edge | Mill edge / Slit edge | Deburring / edge conditioning available. |
Flatness / tolerance | Per ASTM/EN or as agreed | Define flatness for heat-exchanger plates and welded assemblies. |
Delivery condition | Solution annealed (standard) | Pickled/bright annealed depending on thickness/finish. |
Dimension definition: THK × WIDTH × LENGTH.
