Alloy Grade UNS: CAF 766 Heat Resistant Alloy

  • Overview

    CAF 766 is a specialized stainless steel alloy engineered to excel in high-temperature environments. Its formulation provides exceptional resistance to oxidation and creep—common issues that can degrade materials at elevated temperatures. This ensures long-term performance and reliability in demanding conditions where components are subjected to extreme heat and thermal cycling. CAF 766 maintains its strength and structural integrity even under intense thermal stress, making it a valuable choice for applications in industries like aerospace, power generation, and chemical processing, where components must operate reliably under extreme heat.

Frequently Asked Questions

Heat resistant stainless steel refers to alloys designed to maintain mechanical properties and resist oxidation at elevated temperatures.

Applications include furnace parts, heat exchangers, and components in petrochemical plants.

Heat resistant stainless steels can withstand temperatures up to 1,150°C (2,100°F), depending on the grade and exposure time.

High chromium and nickel contents stabilize the austenitic structure and form a protective oxide layer, resisting scale and oxidation.

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.
