Incoloy 800H/HT

Incoloy Alloy 800H/HT is an iron-chromium-nickel alloy, which is resistant to corrosion by many corrosive media. Its high nickel content makes it have good stress corrosion cracking resistance under water-based corrosion conditions. This alloy has the same basic composition as INCOLOY 800 alloy, but the creep rupture strength is significantly higher.Incoloy 800H/HT can be available in Bar, Pipe, Forging, Plate, Fasteners, Coil, Wire, Fitting, etc.

Overview of Incoloy Alloy 800H/HT

Other common names: UNS N08810, W.Nr. 1.4958; UNS N08811, W.Nr. 1.4959

Incoloy Alloy 800H/HT is an iron-chromium-nickel alloy, which is resistant to corrosion by many corrosive media. Its high nickel content makes it have good stress corrosion cracking resistance under water-based corrosion conditions. This alloy has the same basic composition as INCOLOY 800 alloy, but the creep rupture strength is significantly higher. The higher strength is the result of strict control of carbon, aluminum and titanium content and high temperature annealing. 800H/HT modification is to control carbon and grain size to optimize stress fracture performance. Incoloy 800 H has further modified the combined level of titanium and aluminum to ensure the best high temperature performance. The chemical balance of various elements makes the alloy exhibit excellent anti-carburizing, anti-nitriding and anti-oxidation properties. 800H/HT has excellent cold forming performance and stable mechanical properties, and it is not easy to embrittlement even if exposed to high temperature for a long time.
