High carburization resistance
Resists high oxidation & heat
Good strength & corrosion resistance

Description

Description

Overview:

Incoloy Alloy 330, also goes by the name UNS N08330, is composed of iron-chromium-nickel along with silicon added in a deliberately controlled manner. It helps improve the oxidation resistance property. It also flaunts a solid composition & doesn’t harden with heat treatment.

The high chromium & nickel content provides excellent resistance with regards to carburization and oxidation issues. They can be used on a large scale for muffles, heating furnaces, flare tips, bar baskets, alloy grids, gas turbine parts, high-temperature, & boiler fixtures.

Key Features:

Smooth Weldability: Incoloy 330 can easily be welded with the help of conventional processes. Using shielded-metal based arc helps crave off the heavy sections.
Hot/Cold Fabrication: The alloy 330 can easily be hot/cold fabricated with the use of standard stainless steel procedures.
Heavy Machining: Incoloy 330 requires the use of high power for machining as compared to mild steel & needs to be performed with the help of techniques that reduce the work hardening.
Carburization Resistance: The nickel & chromium content present in this alloy provides ample carburization & oxidation resistance.

Possible Alternative Grades:

Incoloy 25-6MO: This super-austenitic alloy houses 6 percent molybdenum & offers amazing resistance to corrosion that occurs in acidic or neutral environments.
Incoloy 800H: Incoloy 800H consists of carbon content that ranges between 0.05 and 0.10 percent of the overall composition. It ensures better creep resistance & stress-rupture resistance.
Incoloy 800: Popular for its use in condensation condition when kept in the ammonia-based acid mediums, the Incoloy 800 is used in water heaters, nuclear generators, or gas coolers.
Incoloy 825: Incoloy 825 is highly resistant to stress-corrosion that comes from oxidation. It also provides resistance to deterioration from phosphoric acid or sulfuric acid.

Frequently Asked Questions:

Is Incoloy 330 used for ore processing industries?

Yes, the Incoloy 330 is generally used for the perlite systems & equipment within the ore processing industries.

Can Incoloy 330 be machined?

Incoloy 330 can be machined but only when kept in the annealed condition. It is also susceptible to hardening during work, which is why low speed needs to be used when cutting.
