Alloy Grade UNS: C12 – Martensitic Alloy

  • Overview

    Alloy Grade UNS C12, also known as J82090 steel or simply C12 steel, is a martensitic alloy containing up to 10% chromium. This composition gives the alloy impressive properties, including good corrosion resistance and high tensile strength. One of its standout features is its ability to perform well in high-temperature environments, making it valuable for applications where heat resistance is crucial. The martensitic structure of C12 steel contributes to its strength and durability, while the chromium content enhances its corrosion-resistant qualities, resulting in a versatile and robust material for various industrial uses.

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.
