Common Spring Materials

Steel (302/301/304/316): Good for general use and moderate corrosion resistance.
Elgiloy: Cobalt-nickel alloy offering exceptional fatigue resistance and high strength.
Hastelloy: Nickel-molybdenum alloy designed for severe chemical and acidic environments.
Inconel: Nickel-chromium alloy ideal for extreme high-temperature and cryogenic duties.
