Alloy Grade UNS: J21890 – Alloy Steel

  • Overview

    J21890 is an alloy steel that offers a balanced combination of strength and corrosion resistance. Its composition, primarily iron and chromium with the addition of up to 1.2% molybdenum, contributes to its versatility and suitability for various applications. The chromium content provides inherent resistance to oxidation and corrosion, while the molybdenum addition further enhances its strength and resistance to pitting corrosion. J21890 exhibits good tensile strength, making it capable of withstanding moderate stresses and loads. This combination of properties makes it a valuable choice for applications where a balance of strength, corrosion resistance, and affordability is desired.

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.
