Alloy family
Incoloy Alloys — Iron-Nickel-Chromium Heat & Corrosion Resistant Grades
Incoloy is an iron-nickel-chromium family with lower nickel than Inconel but better cost efficiency, suited to 800–1100 °C carburising, oxidising and sulphidising atmospheres. Main grades: 800, 800H, 800HT, 825, 926, A-286, 330 and DS.
Why specify this alloy family
Cost efficiency
Iron-rich chemistry lowers costly alloying content
Carburisation resistance
800H / 800HT resist carburisation and creep
Acid resistance
825 handles sulphuric and phosphoric acid
