Incoloy refers to a range of superalloys now produced by the Special Metals Corporation (SMC) group of companies and created with a trademark by the Inco company in 1952. Originally Inco protected these alloys by patent. In 2000, the SMC published a 61-page document entitled "High-Performance Alloys for Resistance to Aqueous Corrosion" highlighting Incoloy, as well as Monel and Inconel products, and their use in fluid environments such as sulfuric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, nitric acid, other acids as well as freshwater environments.

| - Incoloy is een legering van chroom, nikkel en ijzer. Incoloy is austenitisch en goed bestand tegen hoge temperaturen en corrosie. Het vindt vooral toepassing in de scheikundige nijverheid. Het is niet magnetisch. Het is duurder en moeilijker te bewerken dan roestvast staal. Nog beter bestand tegen hoge temperaturen en corrosie, maar nog duurder en moeilijker te bewerken zijn hastelloy en inconel. Incoloy is geen eenduidig materiaal: er zijn nog verschillende samenstellingen die aangeduid worden met drie cijfers, bijvoorbeeld incoloy-825: 42 % nikkel, 21 % chroom, 22 % ijzer, 3 % molybdeen, 2 % koper, 1 % titanium.

- Incoloy är varumärke för flera högtemperaturtåliga, korrosionsbeständiga legeringar av främst järn, nickel, kobolt och krom. De kommer främst till användning inom petrokemiska processanläggningar. Benämningen incoloy kan härledas till en rad av superlegeringar producerade av Special Metals Corporation-koncernen. De är mestadels nickelbaserade, och sammansatta för stor korrosionsbeständighet och styrka vid höga temperaturer. Det finns specifika legeringar för resistens mot särskilda kemiska angrepp (t. ex. legering 020 som är utformad för att vara motståndskraftiga mot svavelsyra eller DS till att användas i värmebehandlingsugnar med reaktiva atmosfärer och många värmecykler).

| - Incoloy refers to a range of superalloys now produced by the Special Metals Corporation (SMC) group of companies and created with a trademark by the Inco company in 1952. Originally Inco protected these alloys by patent. In 2000, the SMC published a 61-page document entitled "High-Performance Alloys for Resistance to Aqueous Corrosion" highlighting Incoloy, as well as Monel and Inconel products, and their use in fluid environments such as sulfuric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, nitric acid, other acids as well as freshwater environments. Incoloy products are mostly chromium-based and mostly nickel-based, and designed for corrosion resistance as well as strength at high temperatures. Incoloy alloys belong to the category of super . Oneadvantage is that Incoloy alloys do not have to be heat treated after welding to restore the corrosion resistance. There are specific alloys for resistance to particular chemical attacks. For example, alloy 020 is designed to be resistant to sulphuric acid, and the DS Incoloy is to be used in heat-treating furnaces with reactive atmospheres and many heat cycles. Incoloy 020 "exhibits excellent corrosion resistance in chemical environments that contain sulphuric acid, chlorides, phosphoric acid and nitric acid." Incoloy 028 "is resistant to both acids and salts. The copper content makes it resistant to sulfuric acid." Incoloy 330 "exhibits good strength at high temperatures and good resistance to oxidation and reduction environments." Incoloy 800 "is capable of remaining stable and maintaining its austenitic structure even after long time exposures to high temperatures". Incoloy 803 is designed for sulphur-rich environments. Incoloy 825 is approved for use in heat exchanger tubes by ASTM B163, and approved for pressure vessel operating temperatures up to 525°C or up to 538°C. It "offers exceptional resistance to corrosion by sulphuric acid and phosphoric acid". Incoloy 908 "has high tensile strength, fatigue crack growth resistance, good weldability, metallurgical stability and ductility, high fracture and impact toughness, [and] low coefficient of thermal expansion... [Its] resistance to oxygen embrittlement... allows hot fabrication without cracking." Incoloy 907 "has high strength and low thermal expansion coefficient at temperatures up to 800°F." Incoloy 945X is designed for chlorine-rich environments. Molybdenum adds crevice corrosion and pitting resistance to Incoloy 945. Incoloy MA956 is made by a mechanical alloying rather than a bulk-melting process; it was studied for space reactor components in the JIMO project. It is difficult to weld and needs to be heated to 200C for forming processes. A special friction welding process has been developed for it. (en)

Incoloy MA956 framställs som en mekanisk legering snarare än i en bulksmältningsprocess, och har utvärderats för komponenter i rymdreaktorn i Jimo-projektet. Den är svår att svetsa och måste upphettas till 200° C för kallformning. Av följande tabell framgår den procentuella sammansättningen av olika legeringsämnen. (sv)
