Alloy Grade UNS: RENE® 220 – Tensile, Rupture, Welding properties

  • Overview

    RENE® 220 is a nickel-based superalloy that distinguishes itself through its exceptional combination of tensile strength, rupture resistance, and weldability. This alloy exhibits superior tensile properties, allowing it to withstand high stresses and maintain its structural integrity under demanding conditions. Its excellent rupture resistance ensures long-term reliability and prevents premature failure in high-temperature applications. Furthermore, RENE® 220 offers good weldability, making it suitable for fabrication and repair processes. This combination of tensile strength, rupture resistance, and weldability makes RENE® 220 a valuable choice for demanding applications in aerospace, gas turbines, and other industries where components must operate reliably under extreme conditions.

Frequently Asked Questions

Vacuum cast alloys are metals melted and poured in a vacuum environment to reduce contamination from gases and ensure high purity and precision.

Used in aerospace, medical implants, nuclear components, and high-performance turbine parts requiring precise composition and minimal inclusions.

Vacuum casting reduces gas porosity, prevents contamination, and enhances alloy quality, especially for reactive or high-performance metals.

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.
