Alloy Grade UNS: HV – Exceptional Strength

  • Overview

    HV is a high-performance nickel-based alloy that incorporates tungsten to achieve exceptional strength at elevated temperatures. This alloy is specifically designed for demanding applications where components must withstand extreme heat and maintain their structural integrity. The addition of tungsten enhances its strength and creep resistance, allowing it to resist deformation and maintain its shape under high-temperature stress. Furthermore, HV exhibits good resistance to carburization and oxidation, preventing degradation and ensuring long-term performance in harsh environments. With a service limit of 1165 degrees Celsius (2130 degrees Fahrenheit), HV offers exceptional strength and reliability in extreme high-temperature applications.

Frequently Asked Questions

Heat resistant stainless steel refers to alloys designed to maintain mechanical properties and resist oxidation at elevated temperatures.

Applications include furnace parts, heat exchangers, and components in petrochemical plants.

Heat resistant stainless steels can withstand temperatures up to 1,150°C (2,100°F), depending on the grade and exposure time.

High chromium and nickel contents stabilize the austenitic structure and form a protective oxide layer, resisting scale and oxidation.

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.
