Inconel 625 AMS 5581 Datasheet
AMS 5581 is an aerospace material specification that outlines the requirements for Inconel 625 in the form of seamless and welded tubing. Inconel alloy 625 is a nickel-based superalloy known for its excellent corrosion resistance, high-temperature strength, and good fabricability. Here are some key characteristics and requirements of Inconel 625 per AMS 5581.
1. Chemical Composition: AMS 5581G ( 2022-06-20) specifies the chemical composition of Inconel 625, including the percentages of various elements such as 62Ni - 21.5Cr - 9.0Mo - 3.7(Cb + Ta). AMS5581G is Alloy tubing, including seamless or welded, that is corrosion and heat-resistant.
2. Mechanical Properties: The specification defines the required mechanical properties of Inconel 625 tube, including tensile strength, yield strength, elongation, and hardness. These properties ensure that the AMS 5581 tubing can perform reliably in aerospace applications.
3. Heat Treatment: AMS 5581 may specify heat treatment procedures for Inconel 625 DIN 2.4668 tubing to achieve the desired metallurgical properties, such as stress relief or annealing. Heat treatment can also affect Inconel 625 AMS 5581 the mechanical and corrosion-resistant characteristics of the material.
4. Dimensions: The specification outlines the dimensions, tolerances, and surface finish requirements for Inconel 625 UNS N06625 tubing to meet specific aerospace industry standards.
5. Quality Control: AMS 5581 includes requirements for testing and quality control to ensure the tubing's conformance to the specified standards. This may involve non-destructive testing, chemical analysis, and mechanical testing. AMS 5581 tubing is typically used in fluid lines requiring high strength and corrosion resistance in the temperature range from cryogenic to 1800°F (982°C).
