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. Rate is the amount of force required for every inch of compression or, for metric springs, millimeter of compression. The higher the rate, the harder it is to compress the spring.
302 stainless steel springs have good corrosion resistance.
316 stainless steel springs have excellent corrosion resistance.
Springs with closed and ground ends sit flat, so they won’t buckle.

Extension Springs with Loop Ends
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. Rate is the amount of force required for every inch or millimeter of extension.
