Alloy Grade UNS: CE3MN, 5A – Duplex Stainless Steel

  • Overview

    CE3MN, also known as 5A, is a duplex stainless steel that offers a compelling combination of high strength and excellent corrosion resistance. This alloy's duplex microstructure, consisting of a balanced mix of austenite and ferrite phases, contributes to its enhanced mechanical properties and its ability to resist various forms of corrosion. CE3MN is particularly well-suited for demanding environments where components are exposed to harsh corrosive conditions, such as seawater and chemical processing applications. Its combination of high strength and superior corrosion resistance makes it a valuable choice for applications where structural integrity and longevity are critical.

  • Typical Uses

    Desalination equipment, oil & gas, chemical processing, and seawater applications.

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.
