Inconel

Inconel

Strength under harsh conditions

Inconel is known for its strength, and high temperature and corrosion resistance. These properties make it an excellent material choice for many applications in the aerospace and chemical industries. Typical applications include aviation thrust reversers and ductwork, industrial pressure sensors and gauges, as well as sodium sulphide manufacturing applications.

KEY APPLICATIONS & USES

  • Aerospace engine and Airframe components in high-temperature locations
  • Heat-generation and heat-protection devices
  • Pressure vessels, sensors and gauges

GRADES

Arnold’s PTM business rolls a range of Inconel grades to your specifications. The most common grades requested by customers include Inconel 600, 601, 625, and X750.

Inconel 600: Excellent strength and oxidation resistance at high temperatures.

Inconel 601: Used in the chemical industry for its strength and corrosion resistance.

Inconel 625: Used extensively in chemical and seawater applications for its strength and corrosion resistance. Excellent weldability and fatigue strength.

Inconel X750: Resistant to many industrial corrosives, both oxidising and reducing at high temperatures. Can be heat treated to a wide range of strengths and properties as needed by your application.
