Alloy Grade UNS: MTEK 35-45MA – Micro Alloy

  • Overview

    MTEK 35-45MA is a specialized micro-alloyed high-temperature material specifically formulated to excel in extremely harsh environments. Primarily composed of nickel and chromium, this alloy incorporates carefully controlled additions of micro-alloying elements to enhance its performance at elevated temperatures. MTEK 35-45MA exhibits outstanding resistance to carburization and coking, making it suitable for applications where components are exposed to carbon-rich atmospheres and high temperatures. Its high melting point of 2380 degrees Fahrenheit further underscores its ability to withstand extreme heat. This combination of properties makes MTEK 35-45MA a valuable choice for demanding applications in industries where resistance to carburization, coking, and high temperatures is critical.

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.
