Corrosion-Resistant Compression Springs
These springs are more corrosion resistant than standard compression springs. They're also easier to compress than standard compression springs. As you squeeze a compression spring, it pushes back to return to its original length. Spring rate is the amount of force required for every inch of compression or, for metric springs, millimeter of compression. The higher the spring rate, the harder it is to compress the spring.
Cobalt-nickel alloy springs have excellent corrosion resistance as well as high strength.

Confined-Space Conical Compression Springs
Install these springs in tight spots. When pushed together, the coils nest within each other, resulting in a compressed length that's equal to about two widths of wire. Springs are stainless steel for corrosion resistance.

Corrosion-Resistant Extension Springs with Loop Ends
Made of stainless steel, these springs are more corrosion resistant than steel springs. They're also easier to extend than steel springs. As you stretch an extension spring, it gets harder to pull. Minimum load is the amount of force required to start to extend the spring. Maximum load is the amount of force required to fully extend the spring. Spring rate is the amount of force required for every inch or millimeter of extension.
302 stainless steel springs have good corrosion resistance.
316 stainless steel springs have excellent corrosion resistance.
