Incoloy 800HT Plate

Incoloy 800HT Plate is an iron-nickel-chromium alloy with the same basic composition as Incoloy 800, with significantly higher creep rupture strength. The higher strength results from close control of carbon, aluminum and titanium contents in conjunction with a high temp anneal. It will not become embrittled even after long periods of usage in the 1200-1600 deg F range where many stainless steels become brittle. It also exhibits excellent cold forming characteristics typically associated with the nickel-chromium alloys.

– Hydrocarbon cracking
– Industrial furnace and boiler components and equipment
