Nickel Alloys

Nickel alloys are a preferred choice for high-performance applications in corrosive, high-pressure, and high-temperature operations. Learn more about our Alloy 718 API, a high-strength, corrosion-resistant nickel-chromium material suitable for sour service applications. At voestalpine Specialty Metals, we’re an industry leader in precision nickel alloy bar for marine environments, oil and gas operations, chemical processing facilities, aerospace manufacturing, and power generation processes.

Key Benefits of Nickel Alloy Bar

Steel and copper can’t compare to the outstanding properties of nickel alloy for extreme environments:

  • Corrosion resistance: Specialized nickel alloys can withstand the boiling acids and high pressures used in petrochemical industries.
  • Equipment durability: Nickel alloys are resistant to scaling, oxidation, and elevated temperatures, protecting critical parts.
  • Reduced downtime: High-performance, abrasion-resistant metals require less maintenance and fewer repairs.
  • Resistance to stress corrosion cracking: Underwater and offshore drilling operations frequently use nickel alloys because of the exceptional resistance to chloride ions in seawater and brackish water.

As an ISO 9001:2015 certified nickel alloy supplier, we offer durable nickel alloy grades for offshore oil and gas and refining processes.

Nickel Alloy Grades for Corrosive Environments

Nickel alloys 718, 625, 725, and 925 are also known as superalloys. They simultaneously resist extreme temperatures, pressures, and corrosives. Trade names include Inconel and Incoloy.

Alloy 718

This nickel-chromium alloy delivers exceptional creep resistance, fatigue resistance, and tensile strength at temperatures ranging from cryogenic to 1,300 degrees Fahrenheit.

Applications include:

  • Exposed wellhead fittings, connectors, and valves
  • Deep drilling tools
  • Critical springs and fasteners
  • Gas turbine parts
  • Subsea risers, manifolds, and other equipment

API variants meet American Petroleum Institute requirements. BOHLER variants have a minimum yield strength of 150 ksi.

Alloy 625

Alloy 625, also known as Inconel 625, is a nickel-based superalloy known for its exceptional strength, corrosion resistance, and high-temperature performance. It is widely used in demanding environments, particularly in the oil and gas sector.

Alloy 725

This high-strength alloy has a higher molybdenum content. It allows for parts with large inner diameters and smaller outer diameters for enhanced production volume.

Alloy 925

This nickel alloy offers unbeatable corrosion resistance, especially for sulfide stress cracking. It’s commonly used in sour gas environments, such as downhole tubing, subsea and exposed valves, and petrochemical safety equipment.
