Inconel X-750 Wire for Custom Springs & Custom Wire Forms

Please note that we do not sell Inconel X-750 or any other materials in raw form. Inconel X-750 wire is a material option for custom springs, etc., manufactured by Peninsula Spring.

Inconel X-750 is a high temperature nickel alloy that exhibits high resistance to oxidation and chemical corrosion. This alloy offers high stress-rupture strength and low creep rates under high stresses at temperatures up to 1500°F (816°C). Alloy X-750 is the most common type of Inconel and is an excellent material of construction for custom springs and wire forms for high temperature applications.

Heat Treating Inconel X-750

To achieve maximum creep, relaxation & rupture strength at temperatures above 1100°F (593°C)

  1. Solution treatment at 2100°F (1149°C); hold for 2 to 4 hours
  2. Air-cool to room temperature
  3. Intermediate age at 1550°F (843°C); hold for 24 hours
  4. Air-cool to room temperature
  5. Final age at 1300°F (704°C); hold for 20 hours
  6. Air-cool to room temperature

To achieve highest room temperature yield strength & tensile ductility

  1. Stress equalization at 1625°F (885°C); hold for 24 hours
  2. Air-cool to room temperature
  3. Precipitation age at 1300°F (704°C); hold for 20 hours
  4. Air-cool to room temperature

Manufacturing Custom Inconel X-750 Springs & Wire Forms

Inconel X750 is used to fabricate custom springs and wire forms for use in very high temperature environments. Common uses include heat-treating fixtures, jet engine components, forming tools, nuclear power plant applications, and extrusion dies. The material is cold drawn and precipitation hardened after fabrication.
