Adinox Overseas is proud to offer the high-performance Incoloy 800HT Plates, one of the best quality alloys that are designed to achieve an impeccable strength and resistance to be oxidized at high temperatures. This product, by the universal standard designation Alloy 800HT is rolled to the ASTM B409 specification and assigned the UNS N08811 number. Their excellent creep- rupture strength; carburization and sulfidation resistance has seen the plates used extensively in heat exchangers, furnaces, petrochemical processing and power generation systems.
Our Incoloy 800HT Sheets and plates are of an iron-nickel-chromium alloy which also has enhanced mechanical properties than its predecessor Incoloy 800H. With improved regulations on the contents of carbon, aluminum and titanium, this alloy can perform well in a temperature that is greater than 1100F (600C). The material has the ability to resist high-stress and long-term exposure to high temperatures therefore making it unique in sensitive use in oil and gas production, chemical refining and aerospace.
The outstanding oxidation resistance and metallurgical stability of Incoloy 800HT Plate is what makes it so unique. By adding chromium, there is extended resistance to corrosion and by including nickel then there is added resistance to scaling and stress corrosion cracking. With this special composition, these plates will be able to withstand the most challenging thermal cycles in terms of their strength and hardness. Its as being a dual certified alloy to ASTM B409 and ASME SB409 further certifies its quality with the quality standards being applied worldwide.
We are manufacturers of UNS N08811 Plates of different sizes, different thicknesses and different finishes to suit different needs of industry. Cold-rolled or hot-rolled, we maintain the precision cutting, finishing and dimensions of these steel sheet. Our production process flows strictly based on the international standards and hence every Incoloy 800HT plate we supply is traceable and with long service life.
We are committed to serving industries worldwide with fast delivery, competitive pricing, and customized dimensions. As a trusted exporter, stockist, and supplier of ASTM B409 UNS N08811 Plates, Adinox Overseas has built a reputation for excellence across Europe, the Middle East, North America, and Asia.
