Product Description

Our offered Incoloy **0/**0H/**0HT is an iron-nickel-chromium alloy having the same basic composition as Alloy **0, 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. The **0H modification was to control carbon (0.*5 to 0.*0%) and grain size to (>ASTM 5) to optimize stress rupture properties. **0HT has further modifications to the combined titanium and aluminum levels (0.*5 to 1.2%) to ensure optimum high temperature properties. The alloy is dual certified and combines the properties of both forms. 

The chemical balance allows the alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres. **0HT will not become embrittled even after long periods of usage in the ********0 deg F range where many stainless steels become brittle. Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with **0HT. When cold formed extensively the grain size produces a visibly undulated surface called "orange peel". **0HT can be welded by the common techniques used on stainless steels. 

Typical applications for the alloy include ethylene pyrolysis, hydrocarbon cracking, cracking furnaces for vinyl chloride, diphenol and acetic acid. The alloy is also used for valves, fittings and other components exposed to corrosive attack from ***0 to ***0 deg F.
