Spring Material: Maraging Steel
Strongest Spring Steel Available
Maraging steel was originally developed for liquefied natural gas vessels on large tankers. Its inherent material lattice structure prevents propagation of cracking when subjected to stress or load. It is the strongest spring steel available and is good for both low and high temperature applications.
Grades / Attributes
For high stress applications, four different alloys (200, 250, 300 and 350) are used. The numbers reference the material’s yield strength, which is superior to other alloys.
Torsion and recoil springs for military tanks.
Maraging steel provides exceptional strength and can work in a range of temperatures.
Not as corrosion resistant as a high nickel content alloy.
