Incoloy alloy 800H -- UNS N08810
1. Chemical composition
Ni - 30.0-35.0; C - 0.05-0.10; Si - 1.0 (Max); Fe - 39.5 (Min); Cu - 0.75 (Max); Mn - 1.5 (Max); Cr - 19.0-23.0; Al - 0.15-0.60; S - 0.015 (Max)
2. Characteristics and applications
Incoloy 800H and 800HT are dual-validated fe-Ni-Cr alloys with the same chemical composition as 800 alloy, but the creep fracture strength of 800H/800HT alloy is greatly improved by controlling the carbon, aluminum and titanium content and annealing at high temperature. Low carbon content also enhances its stress fracture resistance, while adding aluminum and iron improves its high temperature strength. Incoloy 800H and 800 HT are nickel-iron-chromium alloys with high tensile strength due to their aluminum, carbon and titanium components. Incoloy 800H and 800 HT are used in petrochemical, power plants, industrial furnaces, and heat treatment equipment.

2. Characteristics and applications
Nickel-copper alloy with high strength and corrosion resistance. Resistant to seawater, diluted chlorofluoric acid, sulfuric acid and alkali. Widely used in shipbuilding and offshore engineering, salt production, hydrogen carbide and various chemical industry. Monel 400(UNS:N04400,EN:2.4360) is one of the few important materials that can withstand hydrofluoric acid. The alloy has excellent corrosion resistance in fluorine gas, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives. At the same time, it has better corrosion resistance in seawater than copper base alloy.
Applications: seamless water pipes, steam pipes, seawater exchangers and evaporators in power plants, sulfuric acid and hydrochloric acid environments, crude oil distillation, pump shafts and propellers for seawater use equipment, equipment for uranium extraction and isotope separation in nuclear industry, pumps and valves for hydrochloric acid production equipment.
