NC1248 Incoloy 800H (Alloy 800H, UNS N08810) Plate/Sheet

Incoloy 800H (Alloy 800H, UNS N08810) Plate/Sheet Description

Incoloy alloy is a range of superalloys produced by Special Metals Corporation. They are nickel-iron-chromium alloys that are used for applications that require high corrosion resistance and high-temperature strength. Incoloy alloys are quite similar to Inconel alloys but their different composition makes some distinctions in their applications.
Incoloy 800H is an iron-nickel-chromium alloy having the same basic composition as Incoloy 800, with significantly higher creep-rupture strength. The higher strength results from close control of carbon, aluminum, and titanium contents in conjunction with a high-temperature anneal. The 800H modification was to control carbon (0.05 to 0.10%) and grain size to (>ASTM 5) to optimize stress rupture properties. Incoloy 800H has further modifications to the combined titanium and aluminum levels (0.85 to 1.2%) to ensure optimum high-temperature properties. The alloy is dual-certified and combines the properties of both forms.

FAQs

Q1. What is Incoloy 800H Plate/Sheet?

Incoloy 800H (UNS N08810) Plate/Sheet is a high-temperature, corrosion-resistant nickel-iron-chromium alloy known for its excellent strength, oxidation resistance, and carburization resistance at elevated temperatures. It is a modified version of Incoloy 800 with higher carbon content for improved creep resistance.

Q2. What are the key properties of Incoloy 800H Plate/Sheet?

• High-temperature strength – Excellent creep and stress rupture resistance.
• Oxidation and carburization resistance – Performs well in high-heat environments.
• Corrosion resistance – Resists various acids and aggressive environments.
• Good structural stability – Retains mechanical properties at elevated temperatures.

Q3: What is the difference between hot-rolled and cold-rolled Incoloy 800H sheets?

• Hot-Rolled Sheets – Have a rougher surface but better workability and are preferred for high-temperature applications.
• Cold-Rolled Sheets – Offer a smoother finish, better dimensional accuracy, and enhanced mechanical properties.
