Alloy Grade UNS: R30155 – Heat Resistant Alloy

  • Overview

    R30155 is a high-performance alloy specifically formulated to withstand extreme environments where both heat and corrosion resistance are paramount. This alloy exhibits exceptional strength at elevated temperatures, maintaining its structural integrity and resisting deformation even under prolonged exposure to heat. It offers good oxidation resistance, preventing degradation and ensuring long-term performance in high-temperature applications. Furthermore, R30155 demonstrates good resistance to corrosive attack by sulfuric and nitric acids, making it suitable for challenging chemical environments. This combination of high-temperature strength, oxidation resistance, and corrosion resistance makes R30155 a valuable choice for demanding applications in industries where components must withstand extreme 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%.
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.
