Grade 304316 800H Fitting, Material Inconel, Brand FHA

Incoloy 800, 800h, And 800ht are nickel, Iron, Chromium alloys having exceptional durability against carburization and oxidation in high, Temperature exposure and with good strength. These nickel steel alloys are identical except for the higher level of carbon in alloy 800h, And the incorporation of no more than 1. 20 % aluminum and titanium in alloy 800ht. Incoloy 800 was the initial of these alloys and it was slightly modified into incoloy 800h. The modification made was to control carbon . 05, .10% and grain size to optimize stress rupture properties. Incoloy 800ht has more modifications to the combined aluminum and titanium levels . 85, 1. 20% to ensure optimum high temperature properties. The nickel alloy is dual certified 800h/ht and combines the properties of both forms. Incoloy 800h/ht alloy was actually meant for high, Temperature structural applications. These alloys offer protection from embrittlement from precipitation of sigma phase and chloride stress, Corrosion cracking as a result of the nickel content. The corrosion resistance is quite high. In the solution annealed condition, Alloys 800h and 800ht have excellent creep and stress rupture properties. The dual certified 800h/ht alloy is often on hand also with mega mex. Incoloy 800 is mainly employed in various uses with maximum temperatures of 1100 f, Where alloys 800h and 800ht are normally used in temperatures above 1100 f where resistance to creep and rupture is required. The chemical balance allows the nickel steel alloy to exhibit excellent resistance to carburization, Oxidation and nitriding atmospheres. Incoloy 800ht will not become embrittled even after long periods of usage in the 1200, 1600 f range where many stainless steels become brittle.
