Alloy Grade UNS: N-7M – Corrosion and Heat Resistant

  • Overview

    N-7M, also known as N30007, is a nickel-molybdenum alloy engineered for exceptional performance in high-temperature and corrosive environments. Its high molybdenum content, up to 33%, contributes significantly to its resistance to a wide range of corrosive media, including strong acids like hydrochloric acid. This alloy exhibits good tensile strength, maintaining its structural integrity under stress, and performs well at elevated temperatures, making it suitable for demanding applications in chemical processing and other industries where both heat and corrosion resistance are critical. Furthermore, N-7M offers good weldability and castability, providing flexibility in fabrication and design for complex components.

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.
