Alloy Grade UNS: J32550 – Seawater Corrosion Resistance

  • Overview

    FERRALIUM 255 is a duplex alloy that has excellent seawater corrosion resistance and has nearly twice the strength of common stainless steel. This super alloy is also known as J32550 or S32550. It contains up to 27% chromium.

  • Typical Uses

    Centrifuge and dewatering equipment, couplings, heat exchangers, offshore piping systems, paper rolls, pulp digesters, pump and valve components, pressure vessels.

  • MetalTek Grade

    FERRALIUM® 255

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.
