Heat-resistant nickel alloy "Alloy 800H/800T"
High nickel and chromium content provides great resistance to oxidation and carburization at high temperatures!
"Aloy 800H/800T (UNS N08810/N08811)" is a high-nickel heat-resistant steel that possesses excellent strength, corrosion resistance, and oxidation resistance at high temperatures, characterized by high structural stability at elevated temperatures. Furthermore, it is an alloy with high creep strength achieved through grain size control via high-temperature heat treatment and control of C, Ti, and Al content. It also exhibits excellent high-temperature strength and does not suffer from embrittlement due to sigma phase precipitation during high-temperature use, making it widely used for heat-resistant applications. [Features] - Workability at hot and cold temperatures is almost the same as austenitic stainless steel. - Welding is possible using TIG, MIG, and coated arc welding. - Heat treatment: solution heat treatment at 1100–1170°C with rapid cooling / solution heat treatment temperature above 1121°C (UNS N08810). - Excellent corrosion resistance in oxidative corrosive environments such as nitric acid and in molten salts like sodium chloride. - Stress corrosion cracking sensitivity is superior compared to standard austenitic stainless steel. *For more details, please refer to the PDF document or feel free to contact us.*
