Incoloy 800HT
Product Detail
Product Tags
Incoloy 800HT provides outstanding resistance to carburization, oxidation and nitridation conditions. They are not susceptible to embrittlement even after prolong operations up to 1200oF to 1600oF. At this temperature range, many stainless steels exhibit brittleness.

Incoloy 800HT Application fields：
1.Nitrate condenser—Corrosion resistance of Nitric acid
2.Steam heating pipes–Very good mechanical properties
3.Heat up element tube–Very good mechanical properties
4.For the application of up to 500℃ environment, alloy state supplies change to annealing.
