SPRON is a well-balanced material that has better mechanical characteristics (hardness, tensile strength, elongation, relaxation, corrosion resistance, and fatigue limit) than SUS304 and Ni base alloy.
(The data values were measured by SII)

1. Mechanical Characteristic (Fatigue Characteristics)
2. Mechanical Characteristics (Spring Relaxation)
3. Corrosion Resistance
4. Magnetic Characteristics
5. High-Temperature Strength

Fatigue due to both statistical and dynamic loads is very small, thus achieving large spring load by a fine spring. High fatigue strength against repetition makes it resistant to fatigue breaking.

SPRON has superior corrosion resistance.

SPRON has superior characteristics even at magnetic.

SPRON has superior characteristics even at high or low temperatures.
