Alloy Grade UNS: CT15C Low Carbon, Niobium-Strengthened Alloy

  • Overview

    CT15C is a high-temperature alloy specifically formulated to deliver exceptional creep rupture strength at elevated temperatures. This low-carbon, niobium-strengthened alloy surpasses the performance of conventional 20-32Nb/CT15C alloys in resisting creep deformation, a phenomenon where materials deform under sustained stress at high temperatures. With a service limit of 1040 degrees Celsius (1900 degrees Fahrenheit), CT15C maintains its structural integrity and resists deformation even under prolonged exposure to extreme heat. This makes it a valuable choice for demanding applications in industries like aerospace and power generation, where components must operate reliably under high-temperature conditions for extended periods.

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.
