Alloy Grade UNS: HX – Hot Gas Corrosion Resistance

  • Overview

    HX is a specialized high-temperature alloy specifically formulated to provide exceptional resistance to hot gas corrosion. This alloy excels in demanding environments where components are exposed to extremely high temperatures and corrosive gases, such as those encountered in industrial furnaces, gas turbines, and chemical processing equipment. Its unique composition and microstructure provide superior resistance to oxidation, sulfidation, and other forms of hot corrosion, ensuring long-term performance and reliability under extreme conditions. With a service limit of 980 degrees Celsius (1800 degrees Fahrenheit), HX maintains its structural integrity and resists degradation even under prolonged exposure to heat and corrosive gases. This makes it a valuable choice for applications where resistance to hot gas corrosion is paramount.

Non-Ferrous

Non-ferrous alloys are, literally, materials that are not iron-based. While others may provide non-ferrous materials of other materials, the MetalTek family of non-ferrous alloys are copper-based. In general, these materials deliver high strength, and excellent wear and corrosion resistance. They are often found in marine applications and also bushing, bearing, and gear environments.
Stainless Steel Parts

Stainless Steel

Stainless steels owe their ability to resist corrosion primarily to the presence of a passive film on their surface. Chromium is chiefly responsible for formation of the passive film. Iron ceases to rust at approximately 12% chromium content and resistance to oxidizing corrosives increases rapidly with chromium content up to approximately 20%.
Petrochemical Fittings

Specialty Alloys

Specialty Alloys comprise a broad group of materials that deliver properties for more demanding applications, use more exotic or expensive materials, or require special processes to manufacture. Where standard materials may not offer desired performance, specialty alloys (including those that are modified further) may be a sensible selection.
