Alloy Grade UNS: CAF 769 – Heat Resistant Alloy

  • Overview

    CAF 769 is a specialized stainless-steel alloy designed to excel in high-temperature environments. This heat-resistant alloy maintains its strength and structural integrity at elevated temperatures, making it suitable for applications where components are exposed to extreme heat and thermal cycling. CAF 769 resists oxidation and creep, phenomena that can degrade materials at high temperatures, ensuring long-term performance and reliability in demanding conditions. Its ability to withstand heat makes it a valuable choice for applications in industries such as aerospace, power generation, and chemical processing, where components must operate reliably under extreme thermal conditions.

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.
