Incoloy nickel-iron-chromium alloy

Incoloy alloy is a high-strength alloy material based on nickel, iron, and chromium. It belongs to the category of high-temperature and corrosion-resistant alloys. Depending on application requirements, elements such as molybdenum and copper can also be added to the alloy to enhance specific properties. With its excellent physical and chemical properties, Incoloy alloy is widely used in industrial fields requiring high temperature stability, oxidation resistance and strong corrosion resistance.

Incoloy 800H

Incoloy 800H is an austenitic heat-resistant alloy designed for pressure-bearing components at high temperatures. Excellent high-temperature creep strength is achieved through precise control of carbon, aluminum and titanium content and high-temperature annealing at temperatures above 1149°C (grain size ASTM Grade 5 or coarser). The alloy exhibits excellent corrosion resistance in aqueous media below 500°C, as well as good resistance to stress corrosion cracking and machinability. Factory direct sales, shipped from Jiangsu Province.

Frequently Asked Questions (FAQ)

What domestic brand does Incoloy 800H correspond to? What is the difference in ingredients between it and 800?

800H corresponds to 0Cr20Ni32AlTi. It narrows the carbon content to 0.05-0.10%, accurately manages the aluminum and titanium content (total 0.3-1.2%), nickel 30-35%, chromium 19-23%, iron as the balance, and the upper limit of the other elements is basically the same as 800. Fine control of composition serves high-temperature creep performance.

How is the high temperature creep strength of Incoloy 800H obtained?

Under what temperature conditions does Incoloy 800H have good corrosion resistance and strength?

What are the mechanical property data of Incoloy 800H?

The parameter table on this page gives: tensile strength Rm 450N/mm², yield strength Rp0.2 180N/mm², elongation after break A5 35%, density 8.0g/cm³, melting point 1350-1400℃. The room temperature strength value in the table is not high. This is the characteristic of the coarse-grained structure, which results in the more critical high-temperature creep strength.

What forms and specifications is available for Incoloy 800H?

Plate thickness 1-100mm, width 500-2000mm, length 1000-6000mm; rod diameter 5-500mm, length 500-6000mm; pipe outer diameter 6-250mm, wall thickness 0.5-30mm, length ≤12000mm; wire diameter 0.1-10mm, can be made into coiled wire, straight strips or customized electric heating components, shipped by manufacturers in Jiangsu Province, and customization is supported.
