Incoloy 800H and 800HT are modified grades of the original Incoloy 800 alloy, both known for their superior creep and rupture resistance at elevated temperatures. The 800H version includes a higher carbon content, while 800HT features precise control over carbon, aluminum, and titanium to provide enhanced metallurgical stability. Both variants are covered under ASTM B409 and ASME SB409 with UNS designations N08810 and N08811, respectively. These grades ensure reliable strength and corrosion resistance, even after prolonged exposure to high heat, making them suitable for heat exchangers, pressure vessels, and refinery systems.

Our products are trusted by a wide base of customers across sectors. As one of the top Incoloy 800H/800HT Sheets Suppliers, we ensure that each sheet meets rigorous technical standards and customer specifications. The sheets offer resistance to oxidation, carburization, and chloride stress corrosion cracking, making them indispensable for thermal processing, furnace fabrication, and petrochemical operations.

They retain structural integrity under thermal cycling and deliver consistent performance over time. These qualities translate into reduced downtime, extended service life, and lower maintenance costs for our clients.

As a preferred choice among Incoloy 800H/800HT Sheets Stockists, SMM Industries LLP guarantees quick turnaround, high availability, and stringent quality control at every stage of the supply chain.

• Power Generation: Ideal for superheater and reheater tubing where long-term strength at elevated temperatures is required.

• Heat Treating Equipment: Utilized in baskets, trays, and fixtures due to their resistance to scaling and deformation under thermal cycling.

• Nuclear Power Plants: Preferred for reactor core components because of their stability under high radiation and heat exposure.

• Industrial Furnaces: Applied in muffles, retorts, and furnace components thanks to their outstanding heat resistance.

• Gas Turbines: Suited for components exposed to hot combustion gases, maintaining mechanical integrity under stress.

• Pharmaceutical Industry: Trusted for their hygienic properties and resistance to chemical cleaning agents in sterile environments.

• Chemical Processing Plants: Performs well in acidic and chloride-rich atmospheres due to its strong corrosion resistance.

• Offshore Oil Drilling: Reliable in salt-laden environments, offering strength and durability under pressure and corrosion.

• Aerospace Industry: Applied in engine parts where both heat resistance and strength-to-weight ratio are crucial.

Incoloy 800H/800HT Sheets provide a distinct performance edge due to their thermal stability, mechanical strength, and resistance to aggressive environments. The combination of high nickel and chromium content enables the sheets to resist deformation and scaling under fluctuating heat loads. The alloys exhibit minimal creep at high temperatures and are compatible with standard welding, machining, and forming processes. This versatility is one of the reasons industries prefer these sheets over conventional stainless steel or lower-grade alloys in heat-intensive environments.

Across the globe, Incoloy 800H/800HT Sheets are known by different designations depending on national and industrial standards. In the United States, they are classified under UNS N08810 (800H) and N08811 (800HT) in accordance with ASTM and ASME standards. In Europe, they are referenced as X8NiCrAlTi32-21 with Werkstoff numbers 1.4958 and 1.4959.

The United Kingdom refers to them as NA15, while Japan uses the JIS standard designations NCF 800H and NCF 800HT. In China, these alloys fall under GB standard GH3128, and in Russia, they are known as ЭИ673. Despite the varied naming, the material properties remain consistent, ensuring reliable performance and interchangeability in global projects.
