Exhibits tensile strength exceeding that of SUS631-H. As a strain-aging alloy, its strength can be further enhanced by optimizing the cold working rate and heat treatment conditions.

Shows minimal set (loss of elasticity) under both static and dynamic loading, enabling even micro springs to achieve high spring force. After 1 million cycles in a repeated fatigue test, the set ratio is approximately one-sixth that of piano wire.

Exhibits extremely low magnetic permeability, with no significant variation even at higher levels of cold working.

Ideal for components used in measurement and analytical equipment where magnetic interference must be minimized.
