Alloy Grade UNS: CH10 – Austenitic Stainless Steel

  • Overview

    CH10 is a versatile austenitic stainless-steel alloy known for its balanced combination of strength, corrosion resistance, and fabricability. This grade offers good mechanical properties, making it suitable for applications requiring moderate strength and ductility. Its austenitic structure provides excellent corrosion resistance in a variety of environments, making it a reliable choice for components exposed to corrosive elements. CH10 also exhibits good weldability and machinability, offering flexibility in manufacturing processes and facilitating the production of intricate parts. This combination of properties makes CH10 a valuable option for diverse applications where a balance of strength, corrosion resistance, and ease of fabrication 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%.

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.
