Incoloy 800HT Elbows with ability to function under high temperatures and mechanical stress
This modification was to control carbon (.05-.10%) and grain size to optimize stress rupture properties. Incoloy 800HT has further modifications to the combined titanium and aluminum levels (.85-1.20%) to ensure optimum high temperature properties.
Even after prolonged exposure to temperatures between 1200 and 1600 degrees Fahrenheit, where many stainless steels become brittle, 800HT will not become embrittled. The general corrosion resistance is excellent. In the solution annealed condition, alloys 800H and 800HT have superior creep and stress rupture properties. Today, most suppliers, including Mega Mex, only carry the dual certified 800H/HT alloy. The Incoloy 800HT contains 0.5% titanium in the composition. As a result, the Alloy 800HT has higher creep resistance and strength than the 800H. The Incoloy 800 chemical composition makes it oxidation resistant and carburization resistant under high temperatures.
