Alloy Grade UNS: ALLOY 230 – Extreme Heat

  • Overview

    Alloy 230, also known as Haynes 230 or UNS N06230 in wrought form, is a high-performance nickel-chromium-tungsten-molybdenum superalloy recognized for its exceptional properties in extreme heat and corrosive environments. With up to 24% chromium and 15% tungsten, it offers excellent high-temperature strength, superior oxidation resistance, and thermal stability, maintaining integrity at temperatures up to 2100°F (1150°C). A key advantage of Alloy 230 is its excellent fabricability; it can be cold- and hot-worked easily and is suitable for traditional casting methods. Its good ductility allows for easy forming and welding using various techniques. Additionally, Alloy 230 features lower thermal expansion than other high-temperature alloys, making it ideal for applications requiring dimensional stability under 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%.

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.
