Alloy Grade UNS: R31233 – Corrosion and Wear Resistance

  • Overview

    R31233 is a high-performance cobalt-based alloy specifically formulated for demanding applications where a combination of corrosion resistance, wear resistance, and mechanical strength is required. With a chromium content of 25%, this alloy exhibits excellent resistance to various forms of corrosion, making it suitable for harsh environments. Furthermore, R31233 offers exceptional wear resistance, ensuring durability and long-term performance in applications involving friction and abrasion. This alloy also boasts impressive mechanical properties, including high tensile strength, impact toughness, and ductility, making it capable of withstanding significant stresses and impacts without fracturing. This unique combination of properties makes R31233 a valuable choice for industries where components must endure extreme conditions and maintain their structural integrity.

Frequently Asked Questions

Vacuum cast alloys are metals melted and poured in a vacuum environment to reduce contamination from gases and ensure high purity and precision.

Used in aerospace, medical implants, nuclear components, and high-performance turbine parts requiring precise composition and minimal inclusions.

Vacuum casting reduces gas porosity, prevents contamination, and enhances alloy quality, especially for reactive or high-performance metals.

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.
