Alloy Grade UNS: MTEK 25-35WCo – Petrochemical Applications

  • Overview

    MTEK 25-35WCo is a specialized alloy designed for extreme service conditions in petrochemical applications. This alloy pushes the boundaries of conventional heat-resistant materials, enabling operation at significantly higher temperatures and pressures. Its unique composition and microstructure provide exceptional strength and resistance to creep, oxidation, and other forms of high-temperature degradation. With a service limit of 1180 degrees Celsius (2155 degrees Fahrenheit), MTEK 25-35WCo allows for increased efficiency and performance in demanding petrochemical processes, making it a valuable choice for applications such as furnace tubes, reformer tubes, and other critical components in high-temperature, high-pressure environments.

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%.

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.
