Incoloy 800 Chemical Composition
Incoloy 800 Material Properties Overview
As a professional supplier and manufacturer in China, Arialloy supplies competitively priced incoloy 800 products.
Incoloy 800 (UNS N08800 / W.Nr. 1.4876) is an austenitic alloy of nickel, iron, and chromium that combines corrosion resistance, mechanical strength, and stability at elevated temperatures. Its composition contains 30.0% to 35.0% nickel and 19.0% to 23.0% chromium, with at least 39.5% iron and small additions of aluminum and titanium. Carbon content is limited to a maximum of 0.10%. Nickel helps preserve a ductile austenitic structure and improves resistance to chloride stress corrosion cracking. Chromium contributes to resistance against oxidation and aqueous corrosion, while iron helps limit internal oxidation. The alloy retains an austenitic matrix during prolonged thermal exposure, although carbide precipitation can occur and influence its response to subsequent corrosive conditions.
Conventional hot working, cold forming, machining, and welding processes can be used to fabricate incoloy 800. Its ductility supports forming operations, while cold deformation raises strength and hardness. Heat treatment influences grain size and final mechanical properties, making the specified delivery condition an important part of material selection and production.
Incoloy 800 Corrosion Resistance
Incoloy 800 resists general corrosion in many aqueous environments, including nitric acid under suitable conditions. Its chromium content supports passivation, while nickel improves resistance to chloride stress corrosion cracking. This resistance does not imply complete immunity.
Exposure to approximately 540°C to 760°C can cause sensitization, increasing susceptibility to intergranular corrosion in certain aggressive media. Performance therefore depends on thermal history as well as solution chemistry and temperature. Resistance to stress corrosion cracking should also be distinguished from resistance to pitting and crevice corrosion.
Incoloy 800 Mechanical Properties
At room temperature, annealed incoloy 800 offers moderate strength and good ductility. Representative data at 25°C show a tensile strength of approximately 590 MPa (85,500 psi) and a 0.2% offset yield strength of approximately 250 MPa (36,200 psi). Cold working increases strength and hardness, while annealing restores ductility for further forming.
Actual values depend on product form, dimensions, processing history, and heat treatment. These figures are typical reference data and should not be interpreted as guaranteed specification limits.
Incoloy 800 Temperature Characteristics
Incoloy 800 combines resistance to oxidation and carburization with structural stability at elevated temperatures. Its strength and heat resistance support service up to approximately 816°C under suitable conditions, depending on stress, atmosphere, and exposure duration. Its melting range is approximately 1357°C to 1385°C, well above practical operating temperatures.
Strength decreases as temperature rises, and resistance to oxidation alone does not establish an allowable load. Where prolonged loading makes creep and rupture strength decisive, incoloy 800H or incoloy 800HT generally provides better performance.
